A Beginner’s Guide to the MOSFET

2078 5449

A Beginner’s Guide to the MOSFET @ ReiBot.org.

If you need to switch high current and or high voltage loads with a micro controller you’ll need to use some type of transistor. I’m going to be covering how to use a MOSFET since it’s a better option for high power loads. This guide will be just a brief introduction that will discuss how to drive a mosfet in a simple manner with the ultimate goal of making it act like an ideal switch.

Refer to the N or P channel basic wiring schematics and remember the three pins: Gate, Drain, and Source. When I mention something like Gate-Source potential difference, I’m talking about the difference in voltage between the two pins.

  1. I did update that image to fix the blue backing.

  2. and i thought this would be about cats 🙂
