# 2SC5712

**TOSHIBA** · Bipolar (BJT) · SOT-89

2SC5712 from TOSHIBA, in a SOT-89. 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; drive input, with VEBO max 7 V and IB max 0.3 A. |

## CAD (KiCad official)

- Symbol: `2SC5712`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89 (KiCad packages3D, STEP)
- 3D model files: `2sc5712-etched.step` / `2sc5712-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2sc5712.step` / `2sc5712.glb` are the bare package body.
