Transistor identification

[ageman]

Hi I am looking for some help trying to identify an NPN transistor. It is marked TCDL 83-92. Please see attached photo. Any help would be appreciated

Re: Transistor identification

maybe in house number .can you find a parts list for the unit ?

Re: Transistor identification

Hi Petehall

no cannot find any information on the unit

Re: Transistor identification

what is the unit ? are there anymore transistors same number ? if so you could at least work out the pin out .

Re: Transistor identification

Hi pete hall. It is a led ballast unit for an emergency light. There is another transistor marked the same the pin out is as follows:1

pin No

1 Emitter
2 Collector
3 base

Re: Transistor identification

do you have a component tester?

Re: Transistor identification

Yes I have component tester. Details on the attached photo

Re: Transistor identification

so does the board contain anymore of those transistors - ones that work?

Re: Transistor identification

Hi
yes this is the one that is shown on the component tester

Re: Transistor identification

well if you know the spec, what's the problem?

or just stick an NPN ZTX seies in there - thoes can handle serious power.

Re: Transistor identification

I was struggling to find something similar to replace it with.

Re: Transistor identification

any idea on the kind of voltage it has to handle?

maybe a ztx450 would work - but you need to bend the leads a bit.
