SD103AW S4

KUU · Schottky Diodes · SOD-123

SD103AW S4 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, the end marked with the color band; the maximum repetitive peak reverse voltage is 40 V and the maximum average forward rectified current is 350 mA.
2 A passive Anode, the end opposite the color band; the maximum forward voltage is 0.370 V at IF = 20 mA and 0.600 V at IF = 200 mA.

CAD (KiCad official)

  • Symbol: SD103AW S4
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: sd103aw-s4-etched.step / sd103aw-s4-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd103aw-s4.step / sd103aw-s4.glb are the bare package body.

Provenance
