JoeBob,
I am in the same situation. I had my wife call Toshiba in Japan (she is Japanese) and ask for thier SPICE models. They would supply them to me, ONLY if I promised not to share them. I wouldn't and they didn't.
I have to belive that The Japanese use SPICE and they must have models for thier own devices, but I couldn't get my hands on any of them.
To any Japanese people out there reading this forum: HELP!
One possible solution: IF you can find a cross reference of Japanese to American (western) standard part numbers. EG: a 2SC2240 = a 2Nxxxx. (or MJxxxx, TIPxx, etc) Then use the western model for your simulation. Any reliable cross reference should be close enough to use for a SPICE simulation.
You can get the Specs (in .pdf files form) for all the Japanese part numbers off the Toshiba web site.
Another possible solution: SPICE, Practical Device Modeling by Ron Kielkowski. Make sure you ge a copy with the diskette. Then create your own devices models.
Good Luck and let me know if you get a solution.
