BCW89 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 60 V, 100 mA PNP transistor; the datasheet gives a peak base current limit of -200 mA for single pulses with tp ≤ 1 ms. |
| 2 | E | passive | Emitter terminal of the PNP transistor; the emitter-base voltage is limited to -5 V (VEBO, open collector). |
| 3 | C | passive | Collector terminal of the PNP transistor; the collector-base voltage is limited to -80 V (VCBO, open emitter) and the collector current to -100 mA. |
