AGM03N85H from AGM-Semi, in a TO-263. 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 a threshold of 2.0 to 4.0 V (3.0 V typ) at VDS=VGS, ID=250μA. |
| 2 | D | passive | Drain, also connected to the exposed metal tab; 85 V maximum drain-source voltage and 140 A continuous drain current (package limited) at Tc=25℃. |
| 3 | S | passive | Source; body-diode continuous current up to 140 A with VSD of 1.2 V max at IS=20A. |
