Recently concluded testing indicates that running high voltage diodes in oil may allow for operating beyond the forward current ratings (Io).
All cautions apply — we do not recommend exceeding the current rating of any diode without extensive testing in your application, and basically the trick is to keep the diode junctions cool. In other words, strive to get the heat out.
