[ARC5] [BoatAnchors] Question for Smart People: IGBT Transistors

[don davis]

Dave:

What is your application?  Most "switchers" use MOSFETs for low Rdson and
efficient switching.  I designed power converters a lifetime ago (not too
smart).......

Subject: [BoatAnchors] Question for Smart People: IGBT Transistors

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.
