I need to replace this. It's burnt.. I found the same exact one without the identification marks shaved off..
The one I found works fine.. But I need more
Test the gain of the part, get all working limits taking into account Vc, and Ve, Ie and Ib, from the circuit that works fine. then get a transistor that will work similarly

Just to clear this up for everyone.......because I am certainly confused
Are you looking for datasheet on this part?......if so what exact casing is it?.......is it a TO-126 or TO220 package?......also what type of equipment is it out of? ....make? ...mode l#? .....i.e. audio amplifier?....power supply?......rf transmitter output driver stage?......information like this can help us all try and track this part down for you.
......or are you asking for the supply of a quantity of this part?
Measure current with your multimeter. Get all the working currents.
Remove the transistor, solder wires onto the board, then on use the multimeter to measure the currents

Thank you for contacting ON Semiconductor
Your part number is most likely customer special part SPS9599 which has been discontinued. We can not disclose any information regarding custom part numbers. Sorry for any inconvenience caused.

Subject: here is the actual transistor
Description of customer request:
I need your please. I am looking for this part or a substitute for it.. I am sending you a picture..
May want to contact these people and see how much they are selling it for? I have had no dealings with them but looks Exactly like what you have--of course the datasheet goes no where but the description matches all the way to the case TO-92L. https://www.jotrin.com/product/parts/7929
The most important info is WHAT the transistor did in the circuit. Can you show photos of the PCB etc and/or schematic showing what the part does in the circuit, and what the PSU voltages are etc?
That information will allow the choice of one of the common modern transistors to replace it.

Exactly right Mr RB!!
Totally agree with you.
I asked this question several posts above

.....but alas it wasn't answered...... unless of course its a top secret part from one of those latest underground N. Kor nuks that went bang lately..... .... only joking, sorry ken2028
Come on ken2028, what type of equipment is this part out of? .... and we may be able to help a bit more.
No need to be sorry ken2028, I was only trying to lighten the subject with a little joke! .... sorry
......so it's from a door lock control module? ....hmm ....my first thought on this is that this "semiconductors" specification may not be that critical, .....although to confirm that it would be great if you could possibly reverse engineer the circuit schematic from the pcb layout ... ie. draw the case of the transistor as you have done above and follow back each copper track on the pcb (printed circuit board) from each leg of it, one at a time, and draw out any resistors / capacitors / ic pinouts (and their values / colour codes) etc of what each leg joins to, then post your circuit here and we'll have a look.
Also, if you could post a full pcb size picture and close-up picture of each side of the pcb around where this item is located that may help.
Is it a car doorlock module? ..... if so what make / model of car?
