2SB772-P

YFW · Bipolar (BJT) · SOT-89

2SB772-P from YFW, 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 specifies base drive for saturation at IC=-2A with IB=-0.2A (VBE(sat) -1.5 V max) and an emitter-base rating of VEBO -6 V.
2 Collector passive Collector terminal, rated for VCBO -40 V, VCEO -30 V, continuous collector current IC -3 A, and collector dissipation Pc 0.5 W.
3 Emitter passive Emitter terminal of the PNP transistor, referenced by the emitter-base rating VEBO -6 V and the collector-emitter saturation voltage VCE(sat) -0.5 V max at IC=-2A.
