# BC848C

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

BC848C 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 | input | Base terminal of the NPN transistor; the datasheet gives no pin-specific limit, only device ratings such as VEBO 6 V and continuous IC 0.1 A. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet gives no pin-specific limit, only device ratings such as VEBO 6 V and continuous IC 0.1 A. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; the datasheet gives no pin-specific limit, only device ratings such as VCEO 30 V for BC848 and continuous IC 0.1 A. |

## CAD (KiCad official)

- Symbol: `BC848C`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bc848c-etched.step` / `bc848c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bc848c.step` / `bc848c.glb` are the bare package body.
