Thanks for the replies. Seems simple enough. I once used IRF530's in
a 36vdc h bridege motor circuit. They were held to the heatsinks with
plastic push rivets. You could find the blown one easy. It would melt
the push rivet, the solder around its legs, and then slide down about
a quarter inch.
One thing for people new to MOSFETS, use a high enough voltage rated
part. Inductive pulses were killing those 100v fets protected by a
68v znr. The problem was the peak clamping volatage of the znr was
over 100v by a little. Live and learn. IRF540's were rock solid.
