ASDM40N80KQ-R from ASDsemi, 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 limited to ±20 V (VGSS), with threshold of 1 V min to 2.5 V max at VDS=VGS, IDS=250µA. |
| 2 | D | passive | Drain; 40 V maximum drain-source voltage (VDSS) with 80 A continuous drain current at TC=25°C. |
| 3 | S | passive | Source; the 80 A continuous diode forward current (IS) at TC=25°C flows through the body diode from source to drain. |
