SM2T3V3AF

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

SM2T3V3AF from FUXINSEMI, 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 K passive Cathode (marked with the cathode band); unidirectional TVS with 3.3V working peak reverse voltage, 4.22-6.58V breakdown at 10mA, 8.8V max clamping at 22.7A.
2 A passive Anode of the unidirectional TVS diode, connected to the protected line's return/ground side.

CAD (KiCad official)

  • Symbol: SM2T3V3AF
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: sm2t3v3af-etched.step / sm2t3v3af-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm2t3v3af.step / sm2t3v3af.glb are the bare package body.
