Today I had a curious problem, a power mosfet that was good, after mounting it had a resistance gate source of few ohms. Source drain was ok, I have supply a large current gate source until it has opened. Then the mosfet worked correctly.Hi Albert - yes, that seems to be a possibility. Certainly a cause that affects the drain but damages the gate area is something that fits here. Seems like a rare failure, but certainly a possible...
