# AGMH614H

**AGM Semi** · MOSFETs · TO-263

AGMH614H from AGM Semi, in a TO-263. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate. Insulated MOSFET control terminal. Threshold VGS(th)=2.0-4.0 V (typ 2.8 V); absolute maximum VGS=±20 V. Total gate charge Qg≈38 nC and internal gate resistance Rg≈1.6 Ω at VGS=0 V, VDS=0 V, f=1 MHz. |
| 2 | D | passive | Drain. Also electrically connected to the exposed tab (heat slug) of the TO-263 package. Drain-source breakdown voltage BVDSS=60 V; continuous ID=50 A at TC=25°C (33 A at TC=100°C); pulsed IDM=200 A. Body-diode cathode. |
| 3 | S | passive | Source. MOSFET current return and body-diode anode. RDS(on) typ 11 mΩ (max 15 mΩ) at VGS=10 V, ID=20 A. Body-diode forward voltage VSD≤1.2 V at IS=20 A, VGS=0 V. |
| TAB | D | passive | Exposed thermal/electrical tab, internally connected to the Drain (pin 2). Provides the primary heat-sinking path to the PCB copper pour; RθJC=1.9 °C/W. |

## CAD (KiCad official)

- Symbol: `AGMH614H`
- Footprint: `Package_TO_SOT_SMD:TO-263-2`
- 3D model: TO-263 (KiCad packages3D, STEP)
- 3D model files: `agmh614h-etched.step` / `agmh614h-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `agmh614h.step` / `agmh614h.glb` are the bare package body.
