[Kenwood] Kenwood 2SC2509 not standard 2SC2509

Tue, 30 Jul 2002 20:05:38 -0300

	Hello Don, the only 2SC2509 I know has emitter at center pin (tab
also), but I saw a Toshiba data sheet and it specifies also as with
collector in center pin!. I guess it's an error.
It is so strange a component with the same ID changes pin assignment.
Anyway, in the worst case (supposing there are two different pin
assignment for same transistor ID), state your inquiry to that 2SC2509
with emitter at center (tab also) pin.

Good luck
