Mystery Part TO92 marked 2T011
(1/1)
charliedelta:
Trying to find out what the specification are of this part marked 2T011 or maybe 2to11.
Its in a TO-92 package.
I did search everywhere, no hits?
Anyone have any clues. It's in a USA manufactured Ultrasonic leak detector.
Lots of 2n2926's on the board marked in Yellow and Green so its very early vintage.
Thanks
exe:
Do you have a picture of the board and picture of the part?
charliedelta:
Yes I do see attached. The device behind it is the same one with the same markings.
exe:
I'd desolder one of these and put into a transistor tester. This at least will give some info.
My best guess it's a pnp bjt, but not sure which one.
charliedelta:
I pulled the part.
BJT PNP Hfe 215, Ube 693 and Ic 6.2MA on the chinese transistor analyzer.
A BC557 might be a close match, but I have not looked for match exhaustively.
