hongjiacheng · Bipolar (BJT) · SOT-23
BC856B from hongjiacheng, 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 terminal of the BC856B PNP transistor; the datasheet gives an emitter-base voltage limit of VEBO -5.0 V (IC=0, IE=-10 µA). |
| 2 | E | passive | Emitter terminal of the BC856B PNP transistor; the emitter-base breakdown voltage V(BR)EBO is -5.0 V minimum (IE=-10 µA, IC=0). |
| 3 | C | passive | Collector terminal of the BC856B PNP transistor; the BC856 collector-base voltage is -80 V and collector-emitter voltage is -65 V, with collector current limited to -0.1 A. |
