BSS63 from Nexperia, in a SOT-23. 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 | passive | Base terminal of the PNP transistor; the datasheet gives a peak base current limit IBM of -100 mA (absolute maximum). |
| 2 | E | passive | Emitter terminal of the PNP transistor; the emitter-base voltage VEBO is limited to -6 V with the collector open. |
| 3 | C | passive | Collector terminal of the PNP transistor; the collector-emitter voltage VCEO is limited to -100 V (open base) and the collector current IC to -100 mA. |
