[Boatanchors] Question for Smart People: IGBT Transistors

[David Stinson]

Question for Smart People:
One of the specifications for high voltage
IGBT Transistor (thank you, Mr. Harshman
and a letter is on the way) is Vce when the
the transistor is in saturation.  Typically
3 or 4 volts.   Sort of like the newer FETs that
have a very low on-state resistance.

Am I correct to infer that when the IGBT is
saturated "ON," that 4 Volts at Ice is all
the transistor needs to dissipate?
For instance, if sourcing an Amp through
the transistor, IxV = 4 Watts dissipation.

Thanks,
Dave S.
