SMF20CA

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

SMF20CA from hongjiacheng, in a SOD-123FL. 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 A1 passive Bidirectional TVS terminal with 20V reverse stand-off voltage (VRWM), 22.2V to 24.5V breakdown at 1mA and 32.4V maximum clamping at 6.2A; interchangeable with the other terminal.
2 A2 passive Bidirectional TVS terminal with 20V reverse stand-off voltage (VRWM), 22.2V to 24.5V breakdown at 1mA and 32.4V maximum clamping at 6.2A; interchangeable with the other terminal.

CAD (KiCad official)

  • Symbol: SMF20CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: smf20ca-etched.step / smf20ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf20ca.step / smf20ca.glb are the bare package body.
