I have used his devices for years...excellent performance/service.

Use silicon grease and mount on a good conductive surface.

In a full-wave bridge circuit drawing a 2 amp load, each side of the
bridge has 1/2 of the total current, so no one diode draws over 1 amp
with a 2 amp load.

Been there, done that! The first of diodes I bought from Frank in
1981 are still in daily service in a 0-6000v 2 amp supply.
