Frequently Asked Questions
What gain rank does this transistor carry?
This transistor carries the O classification marking, which specifies a DC current gain (h_FE) range of 80 to 160.
What complementary NPN transistor pairs with this part?
The complementary NPN transistor is the Toshiba 2SC3281, typically used alongside the 2SA1302 in complementary symmetrical audio output circuits.
What package outline does this transistor use?
It uses the Toshiba TO-3PL package, which is mechanically compatible with TO-264 mounting footprints and mounts with a single screw through the central tab hole.
Discrete Japanese power silicon from the golden era of analog audio. When a classic amplifier drops an output channel, drop this in and bring the circuit back to life.
