# SI2301CDS

**FUXINSEMI** · MOSFETs · SOT-23

SI2301CDS from FUXINSEMI, 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 | G | input | Gate; gate-source voltage is rated ±8 V absolute maximum with threshold of -0.4 V to -1.0 V at ID = -250 µA. |
| 2 | S | passive | Source of the P-channel MOSFET; drain-source voltage is rated -20 V and continuous drain current -3.0 A. |
| 3 | D | passive | Drain of the P-channel MOSFET; VDS is rated -20 V, continuous ID -3.0 A and pulsed IDM -10 A. |

## CAD (KiCad official)

- Symbol: `SI2301CDS`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `si2301cds-etched.step` / `si2301cds-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `si2301cds.step` / `si2301cds.glb` are the bare package body.
