# BC860C

**Nexperia** · Bipolar (BJT) · SOT-23

BC860C from Nexperia, 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 | input | Base of the PNP transistor; the base drives the device, and the datasheet gives a device-level base peak current limit of -200 mA (IBM). |
| 2 | E | passive | Emitter of the PNP transistor; the datasheet gives a device-level emitter-base voltage limit of -5 V (VEBO) with the collector open. |
| 3 | C | passive | Collector of the PNP transistor; the datasheet gives a device-level collector current limit of -100 mA (IC) and a collector-emitter voltage limit of -45 V (VCEO, open base). |

## CAD (KiCad official)

- Symbol: `BC860C`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bc860c-etched.step` / `bc860c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bc860c.step` / `bc860c.glb` are the bare package body.
