EVVO Semi Single Bipolar Transistors 2SA1987

2SA1987 is a PNP bipolar power transistor paired with 2SC5359 for high-fidelity audio amplifier output stages. It is packaged in a TO-3PL case with dimensions of 20.0 mm in length, 18.0 mm in width, and 26.0 mm in height. The device supports a collector-emitter voltage of 230 V and a continuous collector current of 15 A, with a maximum power dissipation of 180 W at Tc=25℃. Current gain (hFE) ranges from 35 to 160 depending on operating conditions. The transition frequency exceeds 30 MHz, and the collector-emitter saturation voltage is specified up to 1.5 V under Ic=8A and Ib=0.8A. Junction temperature ranges from -55℃ to 150℃, with a thermal resistance of 0.35 °C/W from junction to case.
