BF824W from Nexperia, in a SOT-323. 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 | passive | Base terminal of the PNP transistor; the emitter-base voltage is limited to −4 V (VEBO) with the collector open. |
| 2 | emitter | passive | Emitter terminal of the PNP transistor; the collector current is limited to −25 mA (IC) and the emitter-base voltage to −4 V (VEBO). |
| 3 | collector | passive | Collector terminal of the PNP transistor; the collector-base voltage is limited to −30 V (VCBO) and the collector-emitter voltage to −30 V (VCEO). |
