BCX53-JSM from JSMSEMI, 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 | B | input | Base of the PNP transistor; VEBO max is -5 V and peak base current IBM is -0.2 A. |
| 2 | C | passive | Collector of the PNP transistor; VCBO -100 V, VCEO -80 V, continuous IC -1 A and peak ICM -1.5 A. |
| 3 | E | passive | Emitter of the PNP transistor; VEBO max is -5 V relative to base. |
