can i use general purpose diodes in my driver circuit to power my mosfet irf 640 0r 840 instead of ultrafast recovery diodes?
Missed that.UF4007 is an ultra fast diode
Yes I agree, should have a completely different number.Missed that.
Thought is was just a variant of the standard 1N4007 diode.
It seems to me it's bad form for a manufaturer to use the same number for two entirely different types of diodes.
