I think the MS is MicroSemi, Irvine, CA
http://www.microsemi.com/

They are a major supplier for: Honeywell, GE, HP, Raytheon, BMW, Dell, 
Seagate, Boeing, Guidant, Medtronic, etc.

You could try American MicroSemiconductor

I am working on a power supply with a linear regulator circuit containing 
two MS1700G power transistors that have shorted.  I don't think they are in 
any way exotic, and I'm sure there is a modern replacement.  But I can't 
find any specification information anywhere to begin the replacement 
analysis.  The only internet search results for a MS1700G are from 
distributors that have $250 minimums and are only providing a "quote."  None 
of the normal providers (Digikey, Mouser, JAMECO etc. stock this 
transistor.)  Does anyone have a reference or spec sheet information 
regarding these transistors?

Thanks
