Pks-digiplan sd2 driver IC help please

[asto]

Hi to all!
I have a feeling this search is going to end up to a success.
Well, irving2008 sorry for that. What is printed on the plastic part of this transistor is not clear enough. Besides its date code reads 3283 imagine so many years since this was made. The only thing I know for sure is a TO220 package. No data other than what I see.
The closest result I found today was from a cross ref. source PKS-323-01 But their description is totally some other thing. Not even the code as you can see came close.
So, I keep searching.
I'll have a photo of that part tomorrow.
And hey, Swarfing...would you please send the link where this was described as a darlington. Two pieces of information I now need to get this drive back to life. If this is NPN, collector current and coll/emitter voltage.

cheers
