RF Power Transistor Failed
2 of 2 found this helpful This is an RF power amplifier with the Mitsubishi Semi Conductors logo. It is used in portable comm transceivers. The case and pin-outs are correct with the center emitter terminal and fin connected. However, this transistor failed when the transmitter was keyed for the first time after installation. The base/emitter junction shorted instantly. In my application this transistor is operated near its maximum power rating for short periods only. This transistor is protected by a current limiting varistor that is pasted over the transistor case with silicone heat-sink compound. I subsequently installed an NTE342 which is identical to the 2SC1971 and the device is now operating normally.
I am therefore very concerned regarding the validity of these transistors.

Compact and easily mounts on the cover of the drain bucket.
