multicomp PRO Trans, Npn, 140V, 12A, 150Deg C, 100W; Transistor Polarity Multicomp Pro 2SD425

The 2SD425 is an NPN high-power silicon transistor for general-purpose amplification and switching, housed in a TO-3 case measuring 38.75-39.96 mm high, 19.28-22.23 mm wide, and 7.96-9.28 mm thick. It has a collector-emitter voltage rating of 140 V, a continuous collector current of 12 A, and a power dissipation of 100 W at Tc = 25°C. The thermal resistance from junction to case is 1.75 °C/W. Operating and storage junction temperatures range from -55 to +150 °C. Its DC current gain (hFE) is 40-140 at Ic = 2 A and Vce = 5 V, with a collector-emitter saturation voltage of up to 3 V. The current-gain-bandwidth product is 5 MHz typ. Pin 1 is the base, pin 2 the emitter, and the case is the collector. The part is RoHS compliant.
