MUR3040DT
YFW · Fast Recovery / High Efficiency Diodes · TO-220AB
MUR3040DT from YFW, in a TO-220AB. 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 | PIN1 | passive | Diode terminal of one leg of the common-cathode pair; the datasheet's pinout figure labels it PIN 1 but does not state its function, and the device is rated 400 V repetitive reverse voltage with 30 A average forward current. |
| 2 | PIN2 (case) | passive | Common cathode shared by both diode legs and electrically connected to the mounting tab (case); junction-to-case thermal resistance is 2.5 °C/W typical. |
| 3 | PIN3 | passive | Diode terminal of the other leg of the common-cathode pair; the datasheet's pinout figure labels it PIN 3 but does not state its function, and the device is rated 400 V repetitive reverse voltage with 30 A average forward current. |
