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

There are a couple of other innovative single-die IGBT designs out there, 
that have been shipping now for awhile.  One of my recent favorites is:
http://www.lod.org/Miscellanae/IGBT45GP120B2DF2.pdf
They are shipping this one, but for some reason it's not listed on their 
website yet.

At present, perhaps the most awesome single-die IGBT in a PC-layout package 
is this one:
http://www.lod.org/Miscellanae/PWRX4500VSingle.pdf
This was a custom build for HV modulator switch service, but Powerex has 
now decided to try to market it to the world at large.

The first one works fantastic in 80kHz, 4kW SMPS service, where 20kHz IGBTs 
would fry.  The second, although it exhibits a bit of a turn-off tail, has 
excellent Vds(on) performance for its hold-off voltage and can switch in 
about 250ns.
