SMF18A

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

SMF18A from AnBon, 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 device, marked by the cathode band; SMF18A is the 18 V standoff (VRWM), 20.0-22.1 V breakdown at 1.0 mA, 29.2 V max clamping at 6.8 A Ipp part.
2 A passive Anode of the unidirectional device (the end opposite the cathode band), 200 W peak pulse power TVS.

  • Symbol: SMF18A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf18a-etched.step / smf18a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf18a.step / smf18a.glb are the bare package body.
