AGM Semi · MOSFETs · TO-252
AGM4025D 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 is rated ±20 V (VDS=0V), with threshold VGS(th) of 1.2 V min, 1.7 V typ and 2.5 V max at ID=250μA. |
| 2 | D | passive | Drain (center pin, common with the exposed tab); drain-source voltage is rated 40 V and continuous drain current 125 A at Tc=25℃ (package limited). |
| 3 | S | passive | Source; body-diode source-drain current is rated up to 125 A with a forward voltage of 1.2 V max at IS=15A. |
