Default DTA143 pre-biased transistor

Digikey has SMT package of this transistor available but where can I buy some DTA143's in a traditional 3-lead(non-SMT)-package?


Thanks for the help!
Peter

Hi Peter,

If no one answers, you might try to make your own!

The attachment is from:
http://wwww.ges.cz/sheet/d/

It shows that it's just a small signal PNP with an input resistor.
I would suggest trying 3K9 for the resistor.

Cheers,

Yes, this transistor is VERY plain, a BC560 or similar. Nothing special what so ever except for the built-in resistor.

So I can probably make a replacement with a BC560 and a 3.9K resistor?

I think infact you can use ANY PNP transistor if you have lower voltage than 30 volts.

What is it for? A switch of some kind?

Just make sure the leads go in the right holes, and you're done
