Hello Dan, What I've found at first is only the following data:
T400012208: SILICON CONTROLLED RECTIFIER, 100V V(DRM),35A I(T), TO-208AA
also, there are three manufacturers for it:
American Microsemiconductor Inc., http://www.americanmicrosemi.com
Advanced Semiconductor Inc.,
http://www.advancedsemiconductor.com
Powerex Inc., http://www.pwrx.com
Hope this helps.
Good luck
Guillermo - LU8EYW.
