Hi Terry , All

1.  Attached in new info in my e-mail in box today from IR.  NEW IGBT 
replacement
for the venerable part.

Spec sheet, note Figure 7 (80us pulse transconductance of 600A...   :^D)))  )

Press release from IR.

370W, 600A pulse rated peak Warp II (150kHz) rated IGBT.  Upgraded part to 
IRG4PF50WD part (200W, 204A pulse).  Cost $4.70 / 10K.  Thermal performance 
"significantly" improved over older part, 4 devices supposedly good
for up to 12kW in full bridge.  NPT (PTC) allows paralleling.   No stock at 
Digikey (yet), should be releasing samples PDQ.

2.  Does anyone have a good Pspice model of the TLP250 optocoupler (or can 
point me to one on the web?)  Toshiba does not have one, tried to simulate as
a current controlled voltage source (with diode in series with input) driving a
NPN/PNP totem pole.  Works but transition speeds were 10-20usecs versus 
100ns observed in "juiced" mode.

Thanks
