SMF4L5.0A

FUXINSEMI · ESD And Surge Protection (TVS/ESD) · SOD-123

SMF4L5.0A from FUXINSEMI, in a SOD-123. 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 of the unidirectional TVS, marked by the cathode band; the 5.0V-stand-off SMF4L5.0A clamps at 9.2V maximum.
2 A passive Anode of the unidirectional TVS, on the end opposite the cathode band.
