I have a power mosfet that was shorted.. Due to my carelessness...
A very fine sliver of solder bridged the gate to the drain. Would this usually destroy the said mosfet? Or something else in line with it??
Its a K3556... Is there a simple test for these? The drain pin was cut off, but enough left to make a very fine solder bridge... ughh...
Well scratch that.. If I'm holding the volt meter on the gate side of the mosfet while starting up it will work... i guess I have to trace back and see whats burnt up..
yup. That would pretty much forward bias that fet beyond max!
It's most likely if you didn't over bias the fet and kill it, you may have destroyed the driving circuit since it most likely can only handle a fraction of what is on the drain..
Actually I got lucky.. It was ok after all.
