Need help to ID a transistor

[Govmnt_Lacky]

Found this 4-legged transistor in a drawer here at work and I have not been able to find any info on it:



Any help on what the heck this is would be appreciated. The only other markings are on the side and they read:

3010480
6733 USA

The challenge is ON!

Can it be a 2N6733?

The 4th leg is ground and is connected to the casing. It is usually used in RF transistor. Though this one seems to be a power transistor.

Can it be a 2N6733?

Can you explain how you came up with this?

Bah, I took a guess from the marking, since 4-digits (without the "2N" marking) are usually used to determine american-made transistor (and diode). "3010480" must be a date code or production code.

But I may be wrong.

6733 probably is the date code.  It would be week 33 of 1967, week 33 being the second week of August.

This page cross-references the 3010480 code to a 2N1515. Long discontinued, but a modern equivalent is NTE160.

Thanks James. I found that as well. After some research it looks like it is just a substitute. The pinouts for the 1515 do not match. I would like to find an EXACT match or datasheet for this piece but I doubt one will turn up

I was able to find that this is "possibly" a COMMON EMITTER transistor but still nothing beyond that.

Mystery solved! 

They are PNP Germaniums with an extra leg tied to the case.
