I paged down to GY, it shows 2SC2882Y in case style SC62. If you search SC62
or better SC-62, you get

Does that match your part dimensions and make sense that it would be an npn
gp amp hfe 160-320?

I think gp is for general purpose.

If that doesn't look right, get confused and look here,

The 2SC2882Y differs quite a lot from the 2SD2403 given by Dan previously,
though junction type and the hFE given seems fine. The one I have I'm not sure
it is in good condition, which is why I would like to change it, is showing
~ 260 with my cheap meter.

alltransistors.com says 2SD2003 for "GY" as keyword, so I need some
confirmation. Also I'm searching for the meaning of the "139" marked on my
device.
