# AGM603D

**AGM Semi** · MOSFETs · TO-252

AGM603D 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; gate-source voltage limit is ±20 V, with threshold VGS(th) of 1.2 to 2.2 V at ID=250 µA. |
| 2 | D | passive | Drain, also connected to the exposed tab; VDS max 60 V and continuous ID 130 A at Tc=25 ℃ (package limited). |
| 3 | S | passive | Source; body diode continuous current up to 130 A with VSD max 1.2 V at IS=20 A. |

## CAD (KiCad official)

- Symbol: `AGM603D`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `agm603d-etched.step` / `agm603d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `agm603d.step` / `agm603d.glb` are the bare package body.
