MUR4040PT
Wild Goose · Fast Recovery / High Efficiency Diodes · TO-247
MUR4040PT from Wild Goose, in a TO-247. 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 | Anode | passive | Anode terminal of the 40A super fast recovery rectifier; the datasheet gives a maximum forward voltage of 1.30 V at 20A per element for MUR4040PT. |
| 2 | Cathode | passive | Cathode terminal of the rectifier; the datasheet gives a maximum repetitive reverse voltage of 400 V for MUR4040PT. |
| 3 | Anode | passive | Second anode terminal of the rectifier; the datasheet gives a maximum average forward current of 40 A for the device. |
