Panasonic 2SB1229T

PNP Epitaxial Planar Silicon Transistor in a TO-92 package, designed for driver applications such as voltage regulators, relay drivers, and lamp drivers. The transistor has a collector-to-emitter voltage rating of 50 V, a collector current rating of 2 A, and a collector dissipation of 0.75 W. It features a low collector-to-emitter saturation voltage of up to 0.7 V at IC = 1 A and IB = 50 mA, a hFE current gain ranging from 200 to 400 for the T-rank variant, and a gain-bandwidth product of 150 MHz. Switching times are 60 ns for turn-on time and 30 ns for fall time. The junction temperature ranges from -55°C to 150°C.
