Hello,
Take a look at the part numbers in this link to see if you can use one of them.
I was thinking about trying this component but I dont know if its the same or not…
But i don’t know what the specs are on the original component. Like i say I cannot even find its manufacturer so I could even get a data sheet on it. This is used for a UV Ballast transformer circuit.
I was wondering if this component would work??
Hello @Matthew196
Welcome to the TechForum
I did not find a similar part to that UV ballast on our site.

i dont want the whole Ballast, that would cost OVER $160.00 I can find the complete unit thats not a problem Im trying to get parts to fix my existing one. We had a power outage and when the power company turned everyone on it created a power surge (It WAS NOT due to lightening), it took out the fuse, varistor and one of these transistors tests completely shorted. Yes the surge blew the varistor completely, but I was able to get its part number online and order a new one.
I found the fuse and varistor already I just need this transistor! Thats why I was wondering if a ST13005 would work.
Please let me know. Thanks!

Comparing the specs between the ST13005 and D13005M, the part looks like a possible substitute.
Hi again, there’s one problem I noticed between the D13005M and ST13005. The D13005M schematic looks like this. I hooked it to a transistor checker the good transistor on the board shows up like this. Its like a NPN Transistor with a extra diode.
Now the transistor on the ST13005 shows this diagram, notice how its missing the diode between the Collector and Emitter.
Any other ideas I could use as a good substitute??
Thanks!
Hello Matthew, I couldn’t find a spec sheet that showed the marking D13005M only the marking D13005MD. And I assumed the D suffix called out the integrated diode and without the D I thought the part did not have the diode.
Please take a look at PHD13005,127

Ok last issue… On this transistor the pin outs if your looking at the face of it the side with the numbers and letters on it, the pin out goes Base Emitter Collector, and NOT Base Collector Emitter, like most diodes. Now thats no big deal I can solder wires onto the terminals and put them in the holes if needed but Im guessing thats why you cannot find a direct match for a D13005M transistor is because of the Emmitter and Collector pin outs in reverse.
I confirmed that the emitter is the middle pin as I tried reversing them on the tester and indeed Pin 2 or the middle pin is the emitter. Most transistors go Base Collector Emitter, unfortunately mine is Base Emitter Collector.
Is there any other ideas where I could get that setup or like I say I could solder extension wires to a new transistor and just solder them into the circuit the correct way… No biggie, but it would be nice to have the exact transistor with the Base Emitter Collector setup.
Can you please check on this! Thanks!
Sorry, I can’t find any option with the pinout you are requesting.
