# SI2393DS

**TECH PUBLIC** · MOSFETs · SOT-23-3L

SI2393DS from TECH PUBLIC, in a SOT-23-3L. 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 | GATE | input | Gate of the P-channel MOSFET; gate-source voltage limit is ±20 V with threshold of -1.0 V min to -2.5 V max at -250 µA. |
| 2 | SOURCE | passive | Source of the P-channel MOSFET; continuous source-drain diode current is -8 A max and drain-source voltage is -30 V. |
| 3 | DRAIN | passive | Drain of the P-channel MOSFET; continuous drain current is -8 A (pulsed -80 A) with RDS(on) typ 26 mΩ at VGS=-10 V. |

## CAD (KiCad official)

- Symbol: `SI2393DS`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `si2393ds-etched.step` / `si2393ds-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `si2393ds.step` / `si2393ds.glb` are the bare package body.
