EVVO Semi Single Bipolar Transistors 2SC5949

The 2SC5949 is an NPN silicon bipolar epitaxial planar power transistor designed for high-fidelity audio amplifier output stages, paired with the 2SA2121 PNP transistor. It is housed in a TO-3PL package, with dimensions ranging from 19.8 to 20.2 mm in length and 17.8 to 18.2 mm in width. The device supports a continuous collector current of 15 A and a collector-emitter voltage of 200 V, with a maximum power dissipation of 220 W at Tc=25°C. The transition frequency exceeds 25 MHz, and the collector-emitter saturation voltage is specified at 1.5 to 3.0 V under IC=10 A and IB=1.0 A. The operating junction temperature ranges from -55°C to 150°C, with a thermal resistance from junction to case of 0.35°C/W.
