# AOT2502L

**Alpha & Omega Semicon** · MOSFETs · TO-220

AOT2502L from Alpha & Omega Semicon, in a TO-220. 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, with a maximum gate-source voltage of ±20V and Rg of 1 to 3 Ω (typ 2 Ω). |

## CAD (KiCad official)

- Symbol: `AOT2502L`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `aot2502l-etched.step` / `aot2502l-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `aot2502l.step` / `aot2502l.glb` are the bare package body.
