EVVO Semi Single Bipolar Transistors 2SD1047

2SD1047 is an NPN silicon bipolar epitaxial planar power transistor designed for high-fidelity audio amplifier output stages, paired with the 2SB817 PNP transistor. It is housed in a TO-3PN package with dimensions between 15.1 and 16.5 mm in width, 13.2 to 13.6 mm in lead width, and 19.8 to 20.2 mm in height. The device has a collector-emitter voltage rating of 140 V, a continuous collector current of 12 A, and a power dissipation of 120 W at a case temperature of 25°C. The transition frequency exceeds 15 MHz, and the collector-emitter saturation voltage is specified at 0.3 to 2.0 V under a collector current of 5 A and base current of 0.5 A. The junction-to-case thermal resistance is 0.35 °C/W. The transistor is rated for a junction temperature up to 150°C and operates reliably under high-current, high-voltage, and high-temperature conditions.
