# BC856C

**Guangdong Hottech** · Bipolar (BJT) · SOT-23

BC856C from Guangdong Hottech, 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 PNP transistor; the datasheet rates emitter-base voltage VEBO at -5 V. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the datasheet rates emitter-base voltage VEBO at -5 V and continuous collector current IC at -0.1 A. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; the datasheet rates collector-emitter voltage VCEO at -65 V for BC856 (-45 V for BC857, -30 V for BC858) and collector power dissipation PC at 0.2 W. |

## CAD (KiCad official)

- Symbol: `BC856C`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bc856c-etched.step` / `bc856c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bc856c.step` / `bc856c.glb` are the bare package body.
