SMF3.3A

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

SMF3.3A from KUU, 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 (color band end) of the unidirectional TVS diode, with VRWM 3.3 V, VBR 5.2 V min to 6.0 V max at 10 mA, and VC 8 V at IPP 25 A.
2 A passive Anode of the unidirectional TVS diode, with 200 W peak pulse power (10/1000µs) and IR 400 µA max at VRWM 3.3 V.

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