    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
