Insulated Gate Bipolar Transistor

It is like an NPN bipolar transistor with an FET gate instead of a
bipolar base.  They are voltage controlled instead of current
controlled.  In applications switching more than 400 volts at more
than, say, ten amps they are more efficient than FETs.  I've never
used them so I can't tell you much more.

The fine folks at Digi-Key are more than happy to list them in their
catalog.  Whether they have them on the shelf is another question
altogether.
