# AO3414A

**UMW** · MOSFETs · SOT-23

AO3414A from UMW, 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 terminal; gate-source voltage is rated ±8V absolute maximum, and the device is specified for gate drive down to 1.8V. |
| 2 | S | passive | SOURCE terminal, the reference for the gate-source voltage (VGS rated ±8V) and the return path for the drain current. |
| 3 | D | passive | DRAIN terminal; drain-source voltage is rated 20V and continuous drain current is 4.2A at TA=25°C (RθJA measured on 1 in² FR-4). |

## CAD (KiCad official)

- Symbol: `AO3414A`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ao3414a-etched.step` / `ao3414a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ao3414a.step` / `ao3414a.glb` are the bare package body.
