I would like to create a reverse voltage protection for my 12v 0.1A - 3A (load is changing) DC circuit with minimal voltage drop. According to this Instructable Link. There are 3 ways to do it. Using a Diode, a Schottky diode, or a MOSFET.
It would seems the mosfet is the way to go, but i am not well versed with mosfets and do not know too many of them, so are there any other COMMONLY available mosfets that i can easily find? it would seems the one in the guide is quite hard to find.
worse comes to worst. i will just have to settle for schottkies. Is parralleling 2 schottkies recommended to achieve the current demand?
