BCW30 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 | input | Base terminal of the PNP transistor; the datasheet gives no base-only voltage rating, and the peak base current limit is IBM = −200 mA. |
| 2 | E | passive | Emitter terminal of the PNP transistor; the emitter-base voltage is limited to VEBO = −5 V (open collector). |
| 3 | C | passive | Collector terminal of the PNP transistor; the collector-emitter voltage is limited to VCEO = −32 V and the DC collector current to −100 mA. |
