Help w/rectifier ID?

[cvanc]

My Google-fu seems weak on this one, I'm not finding anything on this rectifier.  Anyone got an idea what this is and where a datasheet can be found?  Thanks, as usual...

Edit: Confirmed. It is a high-voltage, general purpouse rectifier diode in a transistor-like (TO-220-2L) package. The series is called "Stealth" by the looks of the Digikey description.
Remember that a lot of manufacturers only include part of a part number on small packages that can't hold the entire number. This is one of those cases. The full part number is ISL9R8120P2, but on the package they cut a portion of the part number off.

Here is the Digikey page for it, you can find a datasheet for this diode there:

Hope this helps
