BC856 3B from DOWO, 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 BC856B PNP transistor (marking 3B); the datasheet's maximum emitter-base voltage VEBO is -5 V. |
| 2 | EMITTER | passive | Emitter terminal; the datasheet limits are a maximum emitter-base voltage VEBO of -5 V and a maximum continuous collector current IC of -0.1 A. |
| 3 | COLLECTOR | passive | Collector terminal; the datasheet limits for BC856 are a collector-emitter voltage VCEO of -65 V and a collector power dissipation PC of 200 mW. |
