MUR2040CT from LGE, 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 | A1 | passive | Anode of the first rectifier diode, in the positive center-tap (common-cathode) configuration used for the MUR2040CT (400 V VRRM, 10 A per leg at 20 A total). |
| 2 | CT | passive | Common cathode center tap of both diodes, which is electrically connected to the case/tab. |
| 3 | A2 | passive | Anode of the second rectifier diode in the positive center-tap (common-cathode) configuration. |
