Just a couple quick ones
1. Why would you ever want to use a transistor over a MOSFET?? If MOSFETS require less current to operate and can handle several times the load why would you ever want to use hotter, current hungry transistor? Is it price?
2. I want to play with a linear actuator I bought. Its a just for fun project. The actuator is 12vdc, 6 inch stroke with a 10k pot feedback. I bought a round, paper thin, ipod like pot (also 10k) and will use a PIC of some sort (I have many to play with). Id like to use a relay to swap the power and ground for extension and retraction and a MOSFET to actually apply the ground to operate the actuator.
I have a IRF3711z MOSFET and want to make sure that I'm reading the data sheet correctly so it doesn't pop when I try to use it. The actuator draws 4A at max load and the MOSFET is (as I read it) capable of 66A @ 100 degrees C. Is this correct or am I interpreting something wrong? This should be more than capable correct? THANKS!!!
