SMF100A

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

SMF100A from LGE, 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, the end marked by the color band on the unidirectional SMF100A (VRWM 100 V, VBR 111 to 123 V at 1 mA, VC 162 V at 1.23 A IPP).
2 A passive Anode, the end opposite the color band; the unidirectional part conducts forward here with VF max 3.5 V at 25 A.

CAD (KiCad official)

  • Symbol: SMF100A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf100a-etched.step / smf100a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf100a.step / smf100a.glb are the bare package body.
