# AGM655D

**AGM-Semi** · MOSFETs · TO-252

AGM655D 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; absolute maximum gate-source voltage is ±20 V and the threshold voltage VGS(th) is 1.2 V min to 2.2 V max at ID=250 µA. |
| 2 | D | passive | Drain, also connected to the exposed tab; drain-source voltage is rated 60 V and continuous drain current is 15 A at TC=25℃ (package limited). |
| 3 | S | passive | Source; body-diode source-drain current is rated up to 15 A. |

## CAD (KiCad official)

- Symbol: `AGM655D`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `agm655d-etched.step` / `agm655d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `agm655d.step` / `agm655d.glb` are the bare package body.
