Sorry to beat a dead horse (I like horses), but did anybody ever figure out if LTspice can actually simulate reverse diode recovery
properly or not ???
I see Helmut's postings too, (msg_43634), but still
can't quite figure out if he is adding a separate diode
in his model or how it connects to the D-S of the FET model if it does.
BTW, searching the help for "recovery" doesn't seem to come up
with anything relevant.
Thanks,

boB,
The standard SPICE diode model uses Tt to model reverse recovery, and thereby, stored charge. The diode capacitance will also have some effect on the dynamic reverse current. This model is reasonably accurate for abrupt recovery diodes, but may not be useful for a soft recovery diode.
