BF823
Nexperia · Bipolar (BJT) · SOT-23
BF823 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 limiting values include a peak base current IBM of -50 mA and an emitter-base voltage VEBO of -5 V (open collector). |
| 2 | E | passive | Emitter terminal of the PNP transistor; the emitter-base voltage is limited to VEBO = -5 V with the collector open. |
| 3 | C | passive | Collector terminal of the PNP transistor; the limits are VCEO = -250 V (open base), collector current IC = -50 mA and peak collector current ICM = -100 mA. |
