Changjing · Bipolar (BJT) · SOT-23
BC847 1G from Changjing, 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 | BASE | passive | Base terminal of the NPN transistor; base-emitter saturation voltage is 1.1 V at IC=100 mA, IB=5 mA per the datasheet. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; emitter-base breakdown voltage VEBO is 6 V minimum at IE=10 µA. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; for the BC847 the collector-emitter voltage is 45 V and continuous collector current is 0.1 A (maximum ratings). |
