SMF26A

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

SMF26A from hongjiacheng, 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 terminal, marked by the cathode band; connect to the protected line, with VRWM 26 V, VBR 28.9 to 31.9 V at 1 mA and VC 42.1 V at IPP 4.8 A.
2 A passive Anode terminal of the unidirectional SMF26A, opposite the cathode band; connect to ground or the return side, with a maximum forward voltage of 3.5 V at 25 A.

CAD (KiCad official)

  • Symbol: SMF26A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: smf26a-etched.step / smf26a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf26a.step / smf26a.glb are the bare package body.
