SMF43CA

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

SMF43CA 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 A1 passive Bidirectional TVS terminal 1 (no polarity); the SMF43CA has no cathode band, 43 V reverse standoff, 47.8-52.8 V breakdown at 1.0 mA, 69.4 V max clamping at 2.9 A.
2 A2 passive Bidirectional TVS terminal 2 (no polarity); the SMF43CA conducts and clamps in either direction, 200 W peak pulse power (10x1000us).

  • Symbol: SMF43CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf43ca-etched.step / smf43ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf43ca.step / smf43ca.glb are the bare package body.
