SMF40A

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

SMF40A 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 TVS (marked by the cathode band); SMF40A has 40 V reverse standoff (VRWM), 44.4 V min to 49.1 V max breakdown at 1.0 mA and 64.5 V max clamping at 3.1 A Ipp.
2 A passive Anode of the unidirectional TVS; 200 W peak pulse power (10x1000 us at TA=25°C) and operating junction temperature -55 to +150 °C.

  • Symbol: SMF40A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf40a-etched.step / smf40a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf40a.step / smf40a.glb are the bare package body.
