I need help identifying a transistor I pulled out of an UPS.  I have four
of them and am wondering if they're worth keeping.

They look similar to the following ascii drawing:

   / --------- \
  / |         | \  (Hmm, I just held it up to the screen and this is almost
 /o |         | o\  actual size -- not bad huh?)
 \  |         |  /
  \ | E  C  B | /
   \ --------- / 

The entire back is metal the package is plastic.  The manufacturer is
Mitsubishi.  There is a label above the pins that says TYPE QM50HG-H and
NO. 90AC1.

What is it?  What's the rating?  What is it good for?

Many thanks in advance.
