power supply transistor ID

Hello,
I am trying to repair a computer power supply, and of course the part
that burnt up is the only one I cannot identify. It is (I think) a
voltage regulator. It is a 3 pin package attached (screwed) to a
largish heat sink. It has the code k1821 on the face, and there is a
logo that looks like an 'F' over either a 'E' or a 'C' like so F
E
I have looked on NTE and chipdocs with no luck. Thanks!

When I just checked chipdocs, it said:
Fuji 2SK1821 TO220 N channel mosfet 600v 2A 30W

Doesn't seem to be on the Fuji semicon page, so it may be obsolete.

Probably a mosfet 2sk1821. Couldn't find a data sheet.

Some MOSFET's from International Rectifier _may be_ (I am too tired and somewhat
drunk to check) compatible.

As per other post, it's a 2SK1821 TO220, N channel mosfet, 600v 2A 30W

Per IR website, http://www.irf.com
IRFIBC20G is a possible replacement.
