BF824W

Nexperia · Bipolar Transistors - BJT · SOT-323

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).
