# S9014W

**MSKSEMI** · Bipolar (BJT) · SOT-323

S9014W from MSKSEMI, in a SOT-323. 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 S9014W NPN transistor, with emitter-base breakdown voltage V(BR)EBO of 5 V minimum and VBE(sat) of 1 V max at IC=100 mA, IB=5 mA. |
| 2 | EMITTER | passive | Emitter terminal of the S9014W NPN transistor, rated for an emitter-base voltage VEBO of 5 V. |
| 3 | COLLECTOR | passive | Collector terminal of the S9014W NPN transistor, rated for a collector-emitter voltage VCEO of 45 V and a collector current IC of 100 mA. |

## CAD (KiCad official)

- Symbol: `S9014W`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323 (KiCad packages3D, STEP)
- 3D model files: `s9014w-etched.step` / `s9014w-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s9014w.step` / `s9014w.glb` are the bare package body.
