Identify transistor H669A
Hi,
can anyone identify this transistor? Marked H 669A Its in a To 126 size all plastic package but a fair bit thicker, one I have not seen before. (why?) Its an NPN with lead out BCE. Its directly on the heatsink of a power amp in series with a thermistor, so is either part of the bias circuitry or temperature sense. I don't have a schematic. Cheers, Gareth. |
