2SB772-MS

MSKSEMI · Bipolar (BJT) · SOT-89

2SB772-MS from MSKSEMI, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BASE input Base terminal of the PNP transistor; the datasheet gives VBE(sat) of -1.5 V max at IC=-2A and IB=-0.2A and VEB of -6 V in the ratings.
2 COLLECTOR passive Collector terminal; the datasheet limits it to VCBO of -40 V, VCEO of -30 V and IC of -3 A continuous, with PC of 0.5 W.
3 EMITTER passive Emitter terminal; the datasheet gives VEBO of -6 V and V(BR)EBO of -5 V min at IE=-100μA.
