# AO3400MI-MS

**MSKSEMI** · MOSFETs · SOT-23

AO3400MI-MS from MSKSEMI, 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 control input of the N-channel MOSFET, rated for a gate-source voltage of ±12 V with a threshold of 0.5 V min to 1.4 V max. |
| 2 | S | passive | Source terminal of the N-channel MOSFET, with a continuous drain-to-source body diode forward current of up to 6.0 A. |
| 3 | D | passive | Drain terminal of the N-channel MOSFET, rated for a drain-source voltage of 30 V and a continuous drain current of 5.8 A at TA=25℃. |

## CAD (KiCad official)

- Symbol: `AO3400MI-MS`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ao3400mi-ms-etched.step` / `ao3400mi-ms-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ao3400mi-ms.step` / `ao3400mi-ms.glb` are the bare package body.
