Changjing · Bipolar (BJT) · SOT-23
BC848 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 | input | Base terminal of the NPN transistor; the datasheet's emitter-base voltage limit is VEBO 6 V. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; continuous collector current is rated at 0.1 A (IC) maximum. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; collector-emitter voltage VCEO is 65 V (BC846), 45 V (BC847) or 30 V (BC848), with collector power dissipation PC 200 mW. |
