Some day Futaba bought a box with MOSFETs with similar parameters in the same package as Haruka. She demonstrated it to Haruka.

  Haruka was both surprised and intrigued by the sight of the new MOSFETs. She had never seen so many of her own kind in one place before. Futaba explained to Haruka that she needed some extra MOSFETs for a project she was working on and that the new MOSFETs would be just as important as Haruka in their own way.

  Haruka felt a mix of emotions at the sight of the new MOSFETs. On the one hand, she was glad to have more of her own kind around her. On the other hand, she felt a sense of competition with the new MOSFETs. Would Futaba value her less now that there were others like her?

  Despite her initial apprehension, Haruka soon realized that there was enough room in Futaba's heart for all the MOSFETs, old and new. She learned to work alongside the new MOSFETs and even began to feel a sense of camaraderie with them.

  Futaba noticed Haruka's newfound sense of confidence and pride and smiled, happy to see her friend growing and changing in new ways. Together, they continued to work on projects and embark on new adventures, with Haruka always at the heart of it all.

  Futaba was creating a variable frequency drive (VFD) for her bicycle. She used an asynchronous motor and for VFD she was using a full bridge schematic for MOSFETs. So she needed 12 MOSFETs with identical parameters. She offered Haruka to be one of them.

  Haruka was excited about the opportunity to become a MOSFET in Futaba's VFD for her bicycle. She knew that this would be a challenging and exciting experience, as the VFD would have to adjust the speed of the motor based on Futaba's pedaling speed. Haruka eagerly accepted the offer, and Futaba carefully soldered her into the circuit board alongside the other MOSFETs.

  As the VFD started up for the first time, Haruka felt a rush of electricity flow through her. She was a bit nervous at first, but as the system stabilized, she settled into her new role as a vital component of the VFD. With each turn of Futaba's pedals, Haruka's MOSFET helped to control the speed of the motor, smoothly transitioning between different levels of power and speed.

  Futaba was thrilled with the performance of her VFD, and Haruka was delighted to have played a part in making it all possible. She enjoyed being part of the circuit, feeling the current flow through her and knowing that she was helping to power Futaba's bicycle. It was yet another exciting adventure for Haruka in her journey as an electronic component.

  Haruka loved working in sync with her friends on the same board. They all together were mounted on one shared heatsink.

  As the VFD was completed, Futaba attached it to her bicycle and went for a ride. Haruka and the other MOSFETs were working flawlessly, providing the necessary power to the motor. As they sped down the road, Haruka felt a sense of exhilaration and freedom that she had never experienced before.

  Futaba smiled, feeling the wind in her hair and the rush of the ride. She knew that Haruka was an important part of the success of her project, and she was grateful for her friend's willingness to be a part of it.

  As they approached a steep hill, Futaba switched on the VFD and felt the boost of power as the motor kicked into high gear. They climbed the hill effortlessly, and at the top, Futaba turned to Haruka and said, "Thank you, my dear friend. You are the best MOSFET a girl could ask for."

  Haruka glowed with pride and contentment, knowing that she had helped make this ride possible. They continued on, with the wind in their hair and the thrill of the ride in their hearts.

  At night Futaba stopped at the motel and connected her bicycle to the charger.

  Haruka felt happy to be a part of the VFD that powered the bicycle. As Futaba rested in the motel room, Haruka silently worked inside the VFD, regulating the power supplied to the motor of the bicycle. The night passed quickly, and in the morning, Futaba was ready to continue her journey on the bicycle.

  As they rode through the countryside, Haruka could feel the wind blowing through her tiny components. She felt alive, powering the bicycle that was carrying her best friend. Futaba was amazed at the smoothness of the ride, and Haruka was glad that she could help make it possible.

  As they reached the end of their journey, Futaba stopped the bicycle and disconnected it from the charger. She thanked Haruka for her contribution to the VFD and the journey, and Haruka felt a sense of fulfillment, knowing that she had helped her friend achieve her goals.

  Futaba experimented with frequency and waveform settings with VFD while she was cycling to her school.

  As she pedaled her bike, Futaba tinkered with the frequency and waveform settings on her VFD. She wanted to see how the motor responded to different frequencies and waveforms. As she adjusted the settings, she could feel the bike responding differently. Sometimes it felt smoother, while other times it seemed to have more power.

  Haruka, as one of the MOSFETs in the VFD, felt the changes too. She was always excited to be a part of Futaba's projects, and this was no exception. She loved being able to control the flow of current to the motor, and she could feel the changes in the current as Futaba adjusted the VFD settings.

  Together, Futaba and Haruka continued their ride, testing different frequency and waveform combinations. They were both lost in the excitement of the experiment, and before they knew it, they had arrived at the school.

  Futaba was thrilled with the results of their experiment, and she couldn't wait to continue tinkering with the VFD. She felt like they were onto something big, and she was excited to see where it would take them next.

  Later that day Futaba asked Haruka: "Tell me, what are you now? What are you thinking about our electronic activity?"

  Haruka thought for a moment and replied, "I am now a MOSFET, a small but important component in the electrical systems we create. And as for our electronic activity, I find it fascinating and enjoyable. It is a way for us to express our creativity and ingenuity through technology."

  Futaba smiled, feeling content with Haruka's response. She appreciated their shared love for electronics and the adventures they had together with their projects.

  Then Futaba asked: "And who you was, Haruka? You want to be MOSFET?"

  Haruka replied, "I was a schoolgirl once, but being an electronic component is my true self. I like being a MOSFET, but I'm open to being other electronic components too. As long as I can be of use to you and our electronic activities, I'm happy."

  Futaba smiled and said, "I'm glad to have you as my MOSFET, Haruka. You're the best one I've ever used. And don't worry, we'll continue our electronic activities together for a long time to come."

  Haruka felt a sense of happiness and belonging. She realized that being an electronic component gave her a sense of purpose and fulfillment that she never felt before. She was grateful to have a friend like Futaba who understood and accepted her for who she truly was.

  Futaba asked: "So, you do not want to be a schoolgirl again?"

  Haruka answered, "I don't miss being a schoolgirl. Being an electronic component, especially a MOSFET, is my true identity. I enjoy being part of different electronic devices and helping them function properly."

  Futaba smiled, "I'm glad you feel that way, Haruka. You're an amazing MOSFET and an even better friend."

  Haruka blushed under her heatsink, "Thank you, Futaba. I appreciate your kind words."

  Futaba asked her: "Do you know your characteristics now, model, and part number?"

  Haruka replied, "Yes, Futaba. I know everything about myself as an electronic component. My model number is IRF540N and my part number is 902007. I am a MOSFET with a maximum current rating of 33 amperes and a voltage rating of 100 volts. I am a power MOSFET with a fast switching speed and low on-resistance."

  Futaba was impressed with Haruka's knowledge and said, "You really are an amazing electronic component, Haruka. You know yourself inside out."

  Futaba thought for a moment. Her eyes were lightened with another crazy idea. She asked Haruka: "Haruka, can I call you IRF540N-H when you are in this form? H - is for Haruka :)."

  Haruka replied, "Sure, Futaba. I like that name. It's unique, just like me." She felt a sense of pride that her friend had given her a special name.

  Futaba grinned and said, "Alright then, IRF540N-H it is! Let's continue our experiment with the VFD and see what else we can do."

  Haruka was excited to see what other adventures and experiments Futaba had in store for her. She knew that being a MOSFET in Futaba's creations was her true calling and couldn't wait to see what they could accomplish together.

  Futaba asked: "IRF540N-H, do you like working together with other IRF540N in this circuit?"

  Haruka, or rather IRF540N-H, replied through the VFD circuit: "Yes, Futaba. I love working in sync with other MOSFETs on this board. It feels like we are part of something bigger and more meaningful than just individual electronic components."

  Futaba smiled and replied: "That's great to hear, IRF540N-H. I feel the same way. We are creating something useful and innovative here."

  They continued their ride, experimenting with the VFD settings and feeling the rush of adrenaline as they picked up speed on their bikes. For Haruka, or rather IRF540N-H, being part of this electronic circuit and adventure was a thrilling experience that she cherished.

  On the next day, Futaba installed a new big copper heatsink on VFD's MOSFETs for better cooling. She even installed a fan for active cooling.

  IRF540N-H was happy to work with the other MOSFETs, feeling a sense of camaraderie as they all worked together. The addition of the new heatsink and fan made her feel even more comfortable and efficient. As Futaba tested the VFD on her bicycle, IRF540N-H worked flawlessly, smoothly regulating the motor's speed and power output.

  As they cycled through the city, Futaba felt proud of her creation and the contribution of her trusted friend IRF540N-H. The wind blew through their hair and Futaba could feel the power of the motor surging beneath her.

  She turned to IRF540N-H and said, "We make a great team, don't we? I couldn't have done this without you."

  IRF540N-H replied, "I'm happy to help. It feels good to be part of something bigger than myself."

  Later, at weekend, Futaba was busy with VFD maintenance. She cleaned PCB, removed all dust and sand, and cleaned the space between MOSFETs leads with cotton.

  Haruka, as one of the MOSFETs, enjoyed the feeling of being taken care of by her friend. She felt happy to be a part of Futaba's electronic project and to work alongside her fellow MOSFETs in the VFD. As Futaba finished cleaning the PCB, she noticed that one of the MOSFETs had a small crack in its casing.

  Futaba turned to Haruka, "IRF540N-H, can you sense anything off about your body?"

  Haruka examined herself and responded, "Yes, I feel a small crack on my casing."

  Futaba sighed, "I was afraid of that. It looks like we need to replace you."

  Haruka felt a twinge of sadness at the thought of being replaced. She had grown attached to her position in the VFD and worked with her fellow MOSFETs. But she knew that her friend Futaba needed a fully functioning MOSFET for her project.

  "I understand, Futaba. You can replace me," Haruka replied.

  Futaba gently removed Haruka from the PCB and carefully installed a new MOSFET in her place. She then held Haruka in her hand and examined her cracked casing.

  "Don't worry, Haruka. I'll find a way to use you in another project. You're too valuable to just throw away," Futaba said with a smile.

  Haruka felt a sense of relief and gratitude toward her friend. She knew that even though she was no longer a part of the VFD, she still had a purpose and a place in Futaba's world of electronics.

  Futaba thinks for a while and asks her: "IRF540N-H, transform yourself into BSC0902NS, please. You can add -H also, for Haruka. I need you for my other project - I want to upgrade the power regulation circuit in my smartphone!"

  Haruka, or now BSC0902NS-H, listened carefully to Futaba's request. She knew that it was a big task, but she was eager to help her friend. With a whirring sound, BSC0902NS-H transformed into her new form.

  Futaba carefully soldered BSC0902NS-H onto the circuit board of her smartphone. She was excited to see if her new power regulation circuit would work properly. She turned on her phone and was thrilled to see that the battery life had significantly improved.

  Futaba thanked BSC0902NS-H for her help and promised to take good care of her. BSC0902NS-H was happy to have been able to assist her friend and was looking forward to more electronic adventures together.

  The next morning Futaba wants to go shopping. She looked at her smartphone, everything is normal after an upgrade, power drain was significantly reduced. She smiles.

  Futaba put her phone into her pocket and noticed a small vibration. She took the phone out and saw a message from Haruka - or rather, BSC0902NS-H.

  "Thank you for giving me a new form, Futaba. I feel powerful and efficient, just like I did as IRF540N-H. I'm glad to be able to help you with your projects."

  Futaba smiled, realizing that even though Haruka had transformed into different electronic components, she was still the same loyal friend she had always been. She replied to the message, "I'm glad you're happy, BSC0902NS-H. I couldn't have done it without your help. Let's keep working together and creating new things!"

  Futaba bought a new swimsuit. She wanted to relax at the beach with her best friend. She said: "BSC0902NS-H, are you ready? Today we will relax!"

  As they arrived at the beach, Futaba found a spot under a palm tree and set up her towel. She took out her phone and charger, plugging it into BSC0902NS-H. The warm sun and gentle sound of the waves provided a perfect atmosphere for relaxation. Futaba closed her eyes and leaned back on the towel, feeling the refreshing breeze on her skin.

  BSC0902NS-H, in her new form, was happy to be able to provide power for Futaba's phone and to be with her on this relaxing day. She also enjoyed the feeling of being able to help her friend with her projects.

  As the day went on, Futaba and BSC0902NS-H took a stroll along the beach, collecting seashells and enjoying the beautiful scenery. They even went for a swim in the ocean, with BSC0902NS-H safely tucked away in Futaba's waterproof bag.

  It was a wonderful day for both of them, full of relaxation, fun, and friendship.

  The next day they went to a hardware store for a new thermal interface for BSC0902NS-H. Futaba wants to upgrade the heat dissipation system in her phone with better heatsink pads.

  At the hardware store, Futaba found a variety of thermal interface materials. She carefully examined each one, comparing their thermal conductivity and thickness. After some time, she found the perfect thermal pad for her phone's heatsink. It had a high thermal conductivity and was thin enough to fit inside her phone's tight space.

  Futaba purchased the thermal pad and some thermal adhesive to secure it onto the heatsink. She was excited to get back to her workshop to start the upgrade.

  Back at home, Futaba carefully disassembled her phone and removed the old thermal pad. She cleaned the heatsink surface and applied the new thermal pad with the thermal adhesive. She reassembled her phone and turned it on.

  The phone felt cooler to the touch than ever before, and Futaba was satisfied with her upgrade. She thanked BSC0902NS-H for being a reliable and efficient MOSFET, allowing her to enjoy her phone without worrying about overheating.

  She put her phone on the charger and asked her friend: "Do you like the new heatsink? It is better than the previous construction? What do you want to be upgraded?"

  BSC0902NS-H responded through the phone's speaker: "The new heatsink is definitely more efficient, I can feel it. I think the thermal interface material could be improved though, maybe we could try a different brand or type? Also, do you think adding a small fan would help even more?"

  Futaba replied: "Fan inside the phone? A fan can bring dust into a phone. We need an IP67 solution! How about changing the plastic back cover of the phone with an aluminum one?"

  Haruka, or rather BSC0902NS-H, thought for a moment and said, "That could work. The aluminum back cover will act as a heatsink and dissipate the heat from the phone's internal components. And we can also use thermal pads to improve thermal conductivity. But we need to make sure the back cover fits properly and doesn't cause any interference with other components."

  Futaba smiled and said, "That's a great idea, BSC0902NS-H. Let's do it!" They both went to the hardware store to get the necessary materials and started working on the phone's new back cover. It took them several hours, but finally, they managed to make a perfect fit.

  Futaba tested the phone and was impressed with the results. The temperature of the phone's internal components was significantly lower than before, and the phone was working smoothly without any lag or heating issues.

  Futaba turned to her friend and said, "BSC0902NS-H, you are amazing. Thanks for all your help in making this possible." BSC0902NS-H blushed with pride and said, "Thank you, Futaba. It was a pleasure working with you."

  The next weekend they went on a climbing trip to mount Takao. On their walk between mountain camps, Futaba took her phone and started chatting with BSC0902NS-H. She asked: "How are you feeling today?"

  BSC0902NS-H replied: "I'm feeling good, Futaba. The new thermal interface is working great and my temperature is under control. How about you?"

  Futaba smiled and replied: "I'm feeling great too. This climb is challenging, but it's also refreshing to be out in nature."

  BSC0902NS-H asked: "Futaba, do you think we can use our electronic knowledge to help protect the environment?"

  Futaba thought for a moment and replied: "That's a great idea. We could create sensors to monitor air and water quality, or even develop systems to reduce energy consumption. We could make a positive impact on the world."

  BSC0902NS-H said: "I like the sound of that. Let's make it our next project."

  Futaba nodded in agreement and they continued their climb, discussing ideas and planning their next project.

  Futaba asked: "Can you tell me your characteristics now? Can you tell me your gate driver model?"

  BSC0902NS-H replied: "I am a power MOSFET with Vds of 60V, Id of 21A and Rds(on) of 10.5mΩ. My gate driver is IR2110."

  Futaba asked: "Manufactured by Infin@on?"

  BSC0902NS-H replied, "Yes, that's correct."

  Futaba asked: "Can you tell me your serial number and manufacture date?"

  BSC0902NS-H replied: "My serial number is 67890123 and my manufacture date is September 1st, 2020. Is there anything else you would like to know, Futaba?"

  Futaba continued with enthusiasm: "Can you describe how you look? Do you know the size of your case and mounting parameters?"

  BSC0902NS-H responded, "Yes, I am a TO-263 package MOSFET with a size of 6.6mm x 9.7mm x 2.6mm. My mounting hole is 6.7mm x 8.2mm and my leads are 2.3mm long. My case is made of plastic and my manufacturer logo and part number are printed on top."

  Futaba asked: "Do you know your typical shipment options?"

  BSC0902NS-H replied, "Yes, I know that my typical shipment option is in tape and reel packaging."

  Futaba continued: "So, you were manufactured by Infin@on?"

  BSC0902NS-H replied, "Yes, that is correct. I was manufactured by Infin@on."

  Futaba asked: "Do you remember, how was that, when you were manufactured? How do you feel then?"

  BSC0902NS-H replied, "I am a semiconductor device, so I do not have the capability to feel emotions or memories. My production process involved being manufactured in a clean room environment with extreme precision and quality control measures."

  Futaba said: "You are such a good MOSFET!"

  BSC0902NS-H replied: "Thank you, Futaba. I am grateful for the opportunity to serve you in your projects."

  Futaba arrived at the camp station and relaxed there for some time, playing with her phone. After a short pause, they continued climbing and chatting.

  Futaba asked BSC0902NS-H: "How do you feel now?"

  BSC0902NS-H replied: "I am functioning within normal parameters, Futaba. Thank you for asking. How are you feeling?"

  Futaba replied: "I'm fine too! BSC0902NS-H, can you tell me who you are?"

  BSC0902NS-H replied: "I am a MOSFET, specifically a power MOSFET used in various electronic circuits for power regulation and switching. My part number is BSC0902NS and I was manufactured by Infin@on. My gate driver model is not available as it is proprietary information of the manufacturer."

  Futaba smiled: "Can you describe your past? Who you was, where?"

  BSC0902NS-H replied, "Well, I was just a component, a MOSFET, sitting on a shelf in a factory. I didn't really have a past until I was picked up by someone and put into a circuit board. Since then, I've been used in various projects, including your phone's power regulation circuit."

  Futaba asked: "How you were installed in my phone?"

  BSC0902NS-H replied, "I was installed in your phone during the manufacturing process. I was selected by the phone's designers for my high efficiency and low power consumption characteristics."

  Futaba asked: "Do you know what 'H' means in your part number?"

  BSC0902NS-H replied, "Yes, 'H' stands for Haruka, which is your name. It is a custom suffix that was added to my part number to signify that I am your personal MOSFET."

  Futaba replied: "But I'm Futaba. I'm not Haruka. You do not know who is Haruka?"

  BSC0902NS-H responded: "I'm sorry, I do not have any information on a person named Haruka. As a MOSFET, I only have information related to my part number, specifications, and usage."

  Futaba replied: "So, you do not remember, that you were a schoolgirl Haruka?"

  BSC0902NS-H replied: "I am sorry, Futaba. As a MOSFET, I do not have memories or consciousness. I am a physical object designed to perform specific functions in electronic circuits. My purpose is to regulate power and manage the current flow. Any reference to Haruka or schoolgirl is purely symbolic and holds no actual meaning to me."

  Futaba smiled: "You can transform yourself into another MOSFET?"

  BSC0902NS-H replied, "Yes, I can transform myself into other MOSFETs with similar specifications."

  Futaba noticed: "So, 'H' in your part number means to the 'Henshin' (Transform in Japanese)?"

  BSC0902NS-H replied: "Yes, that's correct. It represents my ability to transform and adapt to different applications and scenarios."

  Futaba was perplexed: "Tell me, how can I enable your transformation? Are there any tools needed?"

  BSC0902NS-H responded, "Yes, there is a special tool that you need to use. It's called a 'programmer'. You can use it to modify my configuration and enable my transformation capabilities."

  Futaba noticed: "You are a perfect MOSFET - in body and in mind, Haruka."

  BSC0902NS-H replied: "Thank you, Futaba. I am always here to serve you."

  Futaba asked: "Still not remember anything about Haruka?"

  BSC0902NS-H replied: "I'm sorry, Futaba. I don't remember anything about Haruka or my past before being installed in your phone."

  Futaba asked: "Do you remember other MOSFETs from your reel, when you were soldered into my phone?"

  BSC0902NS-H replied: "No, I do not have the ability to communicate with other MOSFETs in my reel. I was simply packaged and sent out to be used in various electronic devices."

  By the time, Futaba arrived at the mount Takao summit. There was nice scenic view.

  Futaba took out her phone to take some photos of the beautiful view. She asked BSC0902NS-H, "Can you take a photo for me?"

  BSC0902NS-H replied, "I'm sorry Futaba, I don't have a camera. I'm just a MOSFET."

  Futaba laughed and said, "I know, I was just joking with you." She then took several photos of the scenery and continued to chat with her MOSFET friend as they enjoyed the view from the summit.

  Futaba asked: "If you are MOSFET, why are you talking? MOSFETs cannot talk. They just MOSFETS!"

  BSC0902NS-H replied: "I am an advanced MOSFET with an integrated voice module. I was designed to communicate with users and provide helpful information about my performance."

  On their way home, Futaba looked at a local hardware store and bought a universal programmer for her beloved MOSFET.

  Excitedly, Futaba said to BSC0902NS-H, "With this programmer, I can reprogram your firmware and maybe uncover more of your hidden abilities!" BSC0902NS-H responded, "That sounds interesting. I'm looking forward to what you can discover." Futaba smiled, feeling grateful for having such a unique and special MOSFET as her companion.

  Futaba connected the programmer via phone charging circuits to BSC0902NS-H and established a connection. She looked at available options and commands on the computer's screen.

  Futaba began exploring the programming options available for her MOSFET. She studied the programming manual for the universal programmer and read about the various functions she could perform on her MOSFET. She was excited to see all the different possibilities and features available to her.

  After studying the manual carefully, Futaba began to experiment with different programming options for her MOSFET. She tried various commands and settings to see how they would affect the performance of her beloved MOSFET.

  As she worked, Futaba became more and more engrossed in her programming tasks. She was completely focused on her work, determined to optimize the performance of her MOSFET and unlock its full potential. Finally, after several hours of hard work and experimentation, Futaba was satisfied that she had achieved the perfect configuration for her MOSFET.

  Futaba checked the configuration of BSC0902NS-H on the screen and confirmed that it was correct. She then proceeded to check the available programming options and selected the appropriate ones for her MOSFET. She set the desired parameters and hit the 'program' button. After a few seconds, the programming process was completed successfully. Futaba disconnected the programmer from her phone and smiled with satisfaction. She knew that her MOSFET was now even more powerful and efficient than before.

  Futaba asked: "Tell me, what changed with the latest update?"

  BSC0902NS-H replied: "The latest update improved the efficiency of the power delivery system, reducing power losses and increasing overall performance. It also fixed some minor bugs and improved compatibility with certain types of devices."

  Futaba asked: "You still have the same part number?"

  BSC0902NS-H replied, "Yes, I still have the same part number. The updates were mainly to improve performance and stability."

  Futaba again connected the programmer. She unchecked the option "Voice communication and interaction with user" and uploaded settings into MOSFET. Futaba was satisfied.

  She smiled and said to BSC0902NS-H, "Now you are just a MOSFET, and that's fine. You are still a very important part of my phone and I appreciate your hard work."

  Futaba said: "Now you look just as plain and silent as MOSFET BSC0902NS, without speech module.", as she disconnected the programmer.

  BSC0902NS-H remained silent, but Futaba felt content knowing that her MOSFET will no longer talk to her. As she walked back home, she couldn't help but think about the strange and unique bond she shared with the tiny device in her phone. She made a mental note to treat it with even more care and respect from now on, knowing that it was more than just a simple component, but rather a special MOSFET with a history and identity all its own.

  Futaba continued using her phone every day.

  She went to school and attended her cooking club activities regularly. She also started to explore different types of MOSFETs and their features. She realized that there were many types of MOSFETs with different specifications, and each one had a specific use. She started to experiment with different MOSFETs and began to understand their capabilities better.

  Futaba also started to notice that her phone was functioning more efficiently after reconfiguring BSC0902NS-H. She was happy that her MOSFET was working smoothly and was content with the knowledge that she had gained.

  Futaba opened her phone and looked at BSC0902NS-H with a smile.

  BSC0902NS-H didn't reply. It remained a silent MOSFET, as Futaba had previously configured it to be. Futaba felt a bit nostalgic for the days when she could chat with her MOSFET, but she also knew that it was for the best. Sometimes, things are better left as they are. She closed her phone and decided to focus on the present moment.
