EVVO Semi Single Bipolar Transistors 2SA1943

The 2SA1943 is a silicon PNP bipolar transistor designed for high-fidelity audio amplifier output stages and power amplifier applications. It is packaged in a TO-3PL case with a collector-emitter voltage rating of -230 V, a collector current rating of -17 A, and a collector power dissipation of 180 W at Tc=25°C. The junction-to-case thermal resistance is 0.68 °C/W. It has a DC current gain (hFE) of 70 to 140 at IC=-5 A and VCE=-4 V, and a transition frequency of 28 MHz. The device is complementary to the 2SC5200 and meets standard operational requirements for high-power audio applications.
