AGM403DG 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; drive limit is ±20 V gate-source (VDS=0V), with a typical threshold of 1.6 V at ID=250μA. |
| 2 | D | passive | Drain, rated 40 V drain-source and 101 A continuous (package limited) at Tc=25℃; it is also connected to the exposed tab. |
| 3 | S | passive | Source; body-diode source-drain current is rated up to 101 A. |
