MOSFET vs BJT
January 7, 2009
Hi guys. I have to admit i do not know much about these kinds of transistors... i mean, their difference.
I have to get a large current pass through a wire, but after having read articles on wikipedia about mosfet i don't really know why i see them on, say, motor drivers instead of BJT transistors. One thing i don't know about is whether you can find logic-level high-power BJTs but i know there are logic-level FETs, like the IRLD series. But again, if you want to switch a BJT on fully then maybe you could just arrange them into a Darlington i guess.
Hmm...so much confusion. Do these two transistor types have precise PROs and CONs?
