# AGM1099D

**AGM-Semi** · MOSFETs · TO-252

AGM1099D from AGM-Semi, 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, with an absolute maximum gate-source voltage of ±20 V and a threshold voltage of 1.2 V min to 2.2 V max at ID=250µA. |
| 2 | D | passive | Drain (also the tab), rated for 100 V drain-source voltage and 8.0 A continuous drain current at TA=25℃. |
| 3 | S | passive | Source, with a body-diode source-drain current of up to 8.0 A. |

## CAD (KiCad official)

- Symbol: `AGM1099D`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `agm1099d-etched.step` / `agm1099d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `agm1099d.step` / `agm1099d.glb` are the bare package body.
