MOSFETs and How to Use Them |  AddOhms #11



MOSFETs are the most common transistors used today.

Support on Patreon: https://patreon.com/baldengineer

They are switches that can be used an Arduino, BeagleBone, or Raspberry Pi. This is part 2 of a 2 part series, which covers MOSFETs. (Part 1 Covered BJTs).

When it comes down to it, MOSFETs are pretty complicated devices. This video will cover the basics of what you need to use them in your circuit, including calculating if you need a heat sink or not.

Learn what they are and how to use them.

Part 1 (BJTs):

    A very good video, I still think many of these electronic videos need more real-life examples. My initial question here is, "why not use a potentiometer to raise the resistance". My only conclusion is the input voltage may not be constant.

    Hello Adam
    What exactly would I need other than an air core coil to re-energize small N52 Neodymium magnets back to their original strengths.

    Although the video is in English, very interesting, simple and educational; thanks

    Hello. Thanks for the great video. I was hoping to learn a little about MOSFET drivers too. May you please write a quick and short explanation about why do we need them sometimes? Thank you.

    Great video, great graphics, great teaching. I've subscribed – though it's a little advanced for an old newbie like me

    I love it how you broke down the complex systems into easy to understand simplicity. That, and the random humor helps keep things interesting.

    great video! i was wondering, what book do you recommend to learn more on the transistor family?

    Does this MOSFET turn off @0V ? Or we have give negetive pulse voltage to turn off ?

    Pretty Good tutorial. Thanks for sharing. yeah I know it is 4 years old but I just noticed it. 🙂

    where is the answer/link for the power dissipation sayed on the datasheet, 79Watts vs the 2.4Watts calculated?

    I have a Cusine Art Burr Coffe grinder, the mosfet is open, cant read the numbers, what would I use for replacement. No heatsink on mosfet.
