Hello,
I am having a high failure rate on a 2N7000 FET that drives a relay coil.
Please see the attached jpeg. This gate drive is coming from a 5 volt
PIC18F452 pin 5 (RD7/PSP7) Any thoughts greatly appreciated. Note that it
will run for quite awhile, perhaps 20 to 30 thousand cycles before failing
entirely shorted Drain to Source.
Thanks.

Dunno, but a 1N4002 isn't a Schottky.
Yeah, I noticed that as well. It's not my schematic, though. Thanks.
