MUR840 from LGE, in a TO-220AC. 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 | K | passive | Cathode terminal, internally connected to the case/tab; the diagram shows pin 1 tied to the cathode side of the diode symbol. |
| 2 | A | passive | Anode terminal; the package diagram shows the diode symbol with its anode on pin 2 and its cathode toward the case. |
