# AGM55N15D

**AGM Semi** · MOSFETs · TO-252

AGM55N15D 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; threshold VGS(th) 2.5 V min to 4.2 V max at VDS=VGS, ID=250μA, with an absolute maximum of ±20 V gate-source. |
| 2 | D | passive | Drain, also connected to the exposed tab; 150 V maximum drain-source voltage and 23 A continuous drain current at Tc=25℃ (package limited). |
| 3 | S | passive | Source; carries the 23 A continuous current at Tc=25℃ and the body-diode current of up to 23 A. |

## CAD (KiCad official)

- Symbol: `AGM55N15D`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `agm55n15d-etched.step` / `agm55n15d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `agm55n15d.step` / `agm55n15d.glb` are the bare package body.
