# SI2302DS

**TECH PUBLIC** · MOSFETs · SOT-23

SI2302DS from TECH PUBLIC, 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; controls the channel, with VGS rated ±8 V max and threshold VGS(th) of 0.4 V min to 1.5 V max at ID = 250 uA. |
| 2 | S | passive | Source of the N-channel MOSFET; carries the continuous drain current of 2.8 A max (10 A pulsed) and the body diode with VSD of 1.2 V max at IS = 0.75 A. |
| 3 | D | passive | Drain of the N-channel MOSFET; drain-source voltage rated 20 V max, with RDS(ON) of 85 mOhm max at VGS = 4.5 V and ID = 2.8 A. |

## CAD (KiCad official)

- Symbol: `SI2302DS`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `si2302ds-etched.step` / `si2302ds-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `si2302ds.step` / `si2302ds.glb` are the bare package body.
