TIP31C ST Bipolar (BJT)

The TIP31C is an NPN bipolar power transistor in TO-220 through-hole package, featuring 100V collector-emitter voltage and 3A continuous collector current. For selection, verify DC current gain (hFE) characteristics, collector-emitter saturation voltage for conduction losses, transition frequency for switching speed, power dissipation with proper heatsinking, and operating junction temperature from -65°C to +150°C. Features include complementary PNP type TIP32C for push-pull designs, rugged reliability, and through-hole TO-220 package for robust mounting. Ideal for power amplifier output stages, DC motor drivers, relay and solenoid drivers, linear regulators, switching regulators, and general-purpose medium-power switching applications.
