Panasonic 2SB631KF

2SB631K is a PNP epitaxial planar silicon transistor for low-frequency power amplifier applications, housed in a TO-126 package with physical dimensions of 8.0 mm x 4.0 mm x 5.1 mm. It has a collector-to-emitter voltage rating of 120 V, collector current of 1 A, and collector dissipation of 8 W at Tc=25°C. Junction temperature operates up to 150°C. The transistor features a minimum DC current gain (hFE) of 100 at IC=50 mA and a maximum collector-to-emitter saturation voltage of 0.4 V at IC=500 mA and IB=50 mA. Gain-bandwidth product is 130 MHz. It meets RoHS standards.
