Changjing · Bipolar (BJT) · SOT-23
BC847 1E 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; the datasheet gives VEBO of 6 V and a 0.1 A continuous collector current limit, with no separate base current rating. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor, with a maximum emitter-base voltage of 6 V (VEBO) stated in the maximum ratings. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; for the BC847 family the datasheet gives VCBO 50 V, VCEO 45 V, and 0.1 A continuous collector current. |
