SM5404 from LGE, in a DO-213AB. 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 MELF body; the SM5404 blocks up to 400 V DC (VRRM 400 V, VRMS 280 V). |
| 2 | A | passive | Anode, the solderable end opposite the color band; carries up to 3.0 A average forward current (IF(AV) at TA=50) with VF of 1.2 V at 3.0 A. |
