I have a blown Transistor out of an electric wheelchair and cannot find a listing or cross reference for the International Rectifier No. 9319 , any help would be appreciated , this is a TO-220 case Trans. Thanks Phil L.
I don't think this is a transistor, as IR made vanishingly few of them. More likely a voltage regulator or SCR.
If you change your search parameters, this might help.

Indeed it may be a thyristor; however I am currently using IR power mosfets in TO-220 cases. Your number may be a date code or house number too; please post _all_ identifying marks on the part for further research.

That sure doesn't look like an IR part number; if the device was made by IR than that appears to be a customer's code. What brand is the controller? Most medical equipment service houses have cross references for all these parts (we have such a shop in our area that repairs wheelchair controllers and they certainly have manuals with component descriptions and cross- references).
Regards,
Michael

This site suggests that it is in fact a (MOS)FET:

How old is the chair? That number looks suspiciously like a date code, and if so, it's absolutely useless as an identifying mark. It just states when the part was made.
Any other characters/numbers on the part that might give us a clue? Have you tried contacting the manufacturer for replacement parts or identification of the part?
As a last resort, contact an organization that services these chairs. They probably won't give you much advice, but it's worth a shot.
One more last resort, you might have to bite a bullet and pay a service shop to repair it for you.

Why should "I" have to pay for the repair of the OPs power chair?
