# 2SC2412

**hongjiacheng** · Bipolar (BJT) · SOT-23

2SC2412 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 NPN transistor; the datasheet rates the emitter-base voltage VEBO at 7.0 V maximum. |
| 2 | E | passive | Emitter terminal of the NPN transistor; the emitter-base breakdown voltage V(BR)EBO is specified at 7.0 V minimum for IE = 50 µA. |
| 3 | C | passive | Collector terminal of the NPN transistor; the datasheet rates VCBO at 60 V, VCEO at 50 V, collector current IC at 150 mA, and collector power dissipation PC at 200 mW. |

## CAD (KiCad official)

- Symbol: `2SC2412`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `2sc2412-etched.step` / `2sc2412-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2sc2412.step` / `2sc2412.glb` are the bare package body.
