SMF3.3CA

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

SMF3.3CA from BORN, 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 A1 passive Bidirectional TVS terminal 1, connects to the protected data/power line, with VRWM 3.3V max, VBR 4.2-5.8V at 1mA and 440W peak pulse power (8/20us).
2 A2 passive Bidirectional TVS terminal 2, interchangeable with terminal 1 and normally connected to ground, with VRWM 3.3V max and 40A peak pulse current (8/20us).

  • Symbol: SMF3.3CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf3-3ca-etched.step / smf3-3ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf3-3ca.step / smf3-3ca.glb are the bare package body.
