Product Overview
The 2SC3320 is an NPN bipolar power transistor designed for high-voltage, fast-switching applications. It features a 400V collector-emitter voltage rating, 15A continuous collector current, and 80W power dissipation. Its low collector-emitter saturation voltage, high switching speed, and strong surge-current capability make it suitable for demanding power-conversion and driver circuits.
Packaged in a TO-3PNB through-hole package, the 2SC3320 is suitable for heatsink-mounted power designs. It can be used in switching power supplies, electronic ballasts, motor-control stages, solenoid and relay drivers, and other high-voltage switching applications.
