Transistors explained – what they are and what they do
and Field Effect Transistors (FETs). BJTs are controlled by current, while FETs are controlled by voltage. Within these categories, there are further subdivisions such as NPN and PNP BJTs and ...

FET: The Friendly Efficient Transistor
If you want to control it from a 3.3 V MCU that can’t handle the high-side voltage on its pins, you can add a NPN transistor section as shown – this inverts the logic, making it into a more ...
