bad IGBT's found again

[tvtimmy]

I bought( 5 )RJP63G4 igbt's from a guy in san jose,ca for $10.
Thought it was a good deal untill the first one I installed fizzled and went short.
Same for #2. I checked the remaining 3 in diode mode,and nothing!
Checked them in resistance mode, open! How could they even short out??
I then robbed one off another board, and replaced q661 that blew with the second one, and it works as it should.

Re: bad IGBT's found again

What would you suggest to use in place of them.
I had to use a smd one because of the thin 2011 panny.
