Help Identifying this TO-XX Three Lead IC

[chiques]

Hello Everyone,
I was wondering if anyone can give me any tips on identifying the part below. The part itself has printed "C3866 / '69". I searched this via Google but had no luck. Does anyone have any tips?

Put the missing prefix on the transistor - try 2SC3866

Wow, how did you guess that?

Thanks!

I doubt it was a guess. Experienced people just know lots of stuff. That's kinda what they mean by experienced.

ok, well thanks again.

Japanese semiconductor manufacturers save on paint.

The prefix "2S" is omitted on all transistors like 2SAXXX, 2SBXXX and 2SCXXX.
