multicomp PRO Trans, Pnp, -180V, -15A, 150Deg C, 150W; Transistor Polarity Multicomp Pro 2SB554

The 2SB554 is a PNP high-power silicon transistor designed for general-purpose amplifier and switching applications, particularly in 100W high-fidelity audio output stages. It is packaged in a TO-3 case with dimensions of 38.75 to 39.96 mm in height, 19.28 to 22.23 mm in width, and 7.96 to 9.28 mm in thickness. The device has a collector-emitter voltage rating of 180 V, a continuous collector current of 15 A, and a power dissipation of 150 W at 25°C case temperature, derating at 1.2 W/°C above that point. Operating and storage junction temperatures range from -55°C to +150°C. Thermal resistance from junction to case is 0.83°C/W. The transistor is complementary to the 2SD424 and meets RoHS standards.
