Pks-digiplan sd2 driver IC help please

[Swarfing]

It's a power transistor and fairly common.

Hi!
Thanks for the response.
I am confused. Google gives me zero results when entering the part code. It is not in <Find chips > data base.
Do you know of any today's equivalent?
If it is an NPN? Collector current...Source for data maybe?

cheers

Is it? i googled and checked other resources and couldn't find details....3020 throws up a to39 can medium power transistor, but 0320 gets no hits...

I beg your pardon gents, just checked the search result that i did earlier and i was wrong. close i can get is a darlington.

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

Asto i just checked out those sites that sell obsolete parts.

looks like that's a digiplan proprietary part number, common anti-copy practice in those days. given the age & specs of the driver i'd suggest 3 options:

1. trace the circuit to determine if npn or pnp then given the spec of the driver (2.5A, 24v IIRC) choose something appropriate in a modern transistor (6 - 10A Ice-max, Vce 100v+, which is likely to be better anyway on Vce-sat and hfe specs). TBH, given other things have may have died I'd not bother.

2. buy a replacement driver off ebay (or check if members such as JohnS have some left over from upgrades)

3. use this as opportunity to upgrade to modern drivers

It seems I do not have choices here. So I better follow your advise irving but for upgrading I do not have a plan yet. And I think I know of at least one way to test this part off the pcb and see if it is a PNP or NPN.
Thanks.

cheers
