SMF14A

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

SMF14A from DOWO, 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 color band; connects to the positive side of the protected line (VRWM 14.0 V, VBR 15.6 to 17.2 V at 1 mA).
2 A passive Anode of the unidirectional TVS, the end without the color band; connects to the ground or return side (max clamping voltage 23.2 V at IPP 8.62 A).

  • Symbol: SMF14A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf14a-etched.step / smf14a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf14a.step / smf14a.glb are the bare package body.
