MURS420C from LGE, in a SMC(DO-214AB). 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, marked by the color band on the package; maximum DC blocking voltage of 200V for MURS420 with 4.0A average forward rectified current. |
| 2 | A | passive | Anode; the datasheet gives no pin numbers, only that the color band denotes the cathode, and forward voltage is 0.89V maximum (per the VF row) at 4.0A. |
