B772 B772 from LGE, 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=-2 A, IB=-0.2 A and emitter-base rating VEBO of -5 V. |
| 2 | COLLECTOR | passive | Collector terminal; the datasheet rates it for VCBO of -40 V, VCEO of -30 V and continuous collector current IC of -3 A, with VCE(sat) of -0.5 V max at IC=-2 A, IB=-0.2 A. |
| 3 | EMITTER | passive | Emitter terminal, the reference for the datasheet's VCEO (-30 V) and VEBO (-5 V) ratings; total device dissipation PC is 0.5 W. |
