I'm working on a few little 12VDC projects, and am wondering on the logic for choosing different types of transistors... Bipolar vs IGBT vs Mosfet... What makes one of them a clear choice in each application?
I can see bipolar transistors would be ideally suited for for analog/linear applications since current in is proportional to current out
Mosfets seems to be suited best to PWM control
So generally speaking, what are the applications for each?
Side question, If you want to do high side switching of a 12V source from a 5V microcontroller, is there any reasonable way to do this without an optocoupler?
