BC847BQ-7-F from Diodes Incorporated, 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 of the NPN transistor; for the BC847A/B/C the emitter-base voltage is limited to 6.0 V and the continuous collector current to 100 mA. |
| 2 | E | passive | Emitter of the NPN transistor; for the BC847A/B/C the peak emitter current is limited to 200 mA. |
| 3 | C | passive | Collector of the NPN transistor; for the BC847A/B/C the collector-emitter voltage is limited to 45 V, the collector-base voltage to 50 V, and the continuous collector current to 100 mA. |
