Hi all,
due to a half-blown bridge I was forced to think about what happens to a mosfet that gets his polarity reversed (so negative VDS for N-channel part and vice versa, gate is clamped to +-8VGS).
So there is this internal body diode that is not spec'd for the Toshiba 2SK1530 power mosfet.
How can I see wether this diode is shot?
Or asked differently, is a power mosfet usually completely shot when its body diode is fried?
Have fun, Hannes
PS: I was lucky, the other half of the bridge was ok, so all my mosfets got was a sagging rail (sort of half wave rectification).
