Re: NEW IR IGBT (IRG4P50WD replacement), TLP250 Model

Original poster: Terry Fritz <teslalist@xxxxxxxxxxxxxxxxxxxxxxx>

Hi Dave,

Looks like a super cool part!! Unfortunately, it is not available anywhere yet... I see they spill a lot of "secrets" now days though ;-))

Why not just use the voltage controlled switch in spice. You can set on and off voltages and turn on and off times directly. A few extra parts can fake all the loads and stuff

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.
