# AOD403

**ElecSuper** · MOSFETs · TO-252

AOD403 from ElecSuper, 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 | Gate | input | Gate of the P-channel MOSFET, with gate-source voltage VGS rated at ±25 V. |
| 2 | Drain | passive | Drain of the MOSFET, rated for a drain-source voltage BVDSS of -30 V and a continuous drain current of -62 A at TC=25°C. |
| 3 | Source | passive | Source of the MOSFET, the reference terminal for the ±25 V gate-source voltage rating. |

## CAD (KiCad official)

- Symbol: `AOD403`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `aod403-etched.step` / `aod403-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `aod403.step` / `aod403.glb` are the bare package body.
