New to me. But they don't seem to be any better than schottkies.



An interesting spec is "reverse recovery time / step recovery"


Well, 300 pA typical / 30 nA max leakage at 120V, 25 C isn't bad for a

2A diode.

Schottkies would have real trouble with that--the lowest leakage one I can find immediately is the RB068MM100, whose leakage is 400 nA max @

100V, 25 C.

The forward recovery looks very nice: 685 mV typ at dI/dt = 20A/us.

Yeah, pretty quick for a PN device.

Overall a pretty good one, I think.

Cheers
