EVVO Semi Single Bipolar Transistors KSA940

KSA940 is a PNP bipolar power transistor paired with the KSC2073 NPN transistor for use in high-fidelity audio amplifier driver stages. It is packaged in a TO-220W case with dimensions of 10.0 mm width, 15.3 mm height, and 4.25 mm thickness. The device has a collector-emitter voltage rating of 150 V, a continuous collector current of 1.5 A, and a power dissipation of 25 W at 25°C case temperature. Its DC current gain ranges from 40 to 140 at 500 mA collector current. The transition frequency exceeds 4 MHz, and the collector-emitter saturation voltage is 1.5 V at 500 mA collector and 50 mA base current. The junction-to-case thermal resistance is 0.30 °C/W. The part operates with a junction temperature range of -55°C to 150°C and meets standard thermal and electrical reliability criteria for high-power applications.
