# AOD4286

**Alpha & Omega Semicon** · MOSFETs · TO-252

AOD4286 from Alpha & Omega Semicon, in a TO-252. 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, rated for a maximum gate-source voltage of ±20V with a threshold of 1.7V to 2.9V. |
| 2 | D | passive | Drain terminal (also the exposed tab), rated for 100V drain-source voltage and 14A continuous drain current at TC=25°C. |
| 3 | S | passive | Source terminal, carrying the 14A continuous drain current at TC=25°C and the body-diode current of up to 14A. |

## CAD (KiCad official)

- Symbol: `AOD4286`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `aod4286-etched.step` / `aod4286-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `aod4286.step` / `aod4286.glb` are the bare package body.
