As in:

=A0=A0 =A0 =A0 =A0 MBRS2H100T3G:=A0100 V, 2.0 A Schottky Rectifier

         http://www.onsemi.com/pub_link/Collateral/MBRS2H100.REV1.PDF

"The Schottky Rectifier employs the Schottky Barrier principle in a
metal-to-silicon power rectifier. It features epitaxial construction
with oxide passivation and metal overlay contact.

The Schottky Rectifier is ideally suited for low voltage, high
frequency switching power supplies, free wheeling diodes and polarity
protection diodes."

Note that "soft recovery" and "fast recovery" are NOT mutually exclusive.
A non soft recovery diode will have a very hard and rapid turn off
"knee" which leads to high dx/dt transistions which stress components
and increase em emissions.
