Hello,

I'm looking for the datasheet of the TP9788
http://img686.imageshack.us/img686/1032/tp9788.jpg but it wasn't anywhere to
be found.
Doe's anybody knows the dates of this transistor?

Thanks
Hansjoerg

Please do not double-post in English and German speaking groups. Someone
already gave you the answer in a German NG.

Right; a four-lead body .380" OD, on a 0.25"W isolated flange, with
mounting holes on 0.75' centres ~ SOT123. For 28MHz CW; was originally
from TRW.
