BC856A_R1_00001 from PANJIT International, 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 PNP transistor; the emitter-base voltage is limited to -5 V (VEBO) and the base drives collector current up to -100 mA continuous. |
| 2 | Emitter | passive | Emitter terminal of the PNP transistor; emitter-base voltage is rated at -5 V (VEBO) and the emitter carries the collector current, rated at -100 mA continuous and -200 mA peak. |
| 3 | Collector | passive | Collector terminal of the PNP transistor; collector-emitter voltage is rated -65 V (BC856), -45 V (BC857) or -30 V (BC858/BC859), with -100 mA continuous and -200 mA peak collector current. |
