SM5404

LGE · Diodes - General Purpose · DO-213AB

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.
