CUS10S30

DOWO · Schottky Diodes · SOD-323

CUS10S30 from DOWO, in a SOD-323. 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 by the color band; reverse blocking voltage VRRM/VDC is 30 V and average forward current is 1 A.
2 A passive Anode, marked '+' on the package drawing; forward voltage is 0.550 V at IF = 1.0 A and 0.875 V at IF = 3.0 A.

CAD (KiCad official)

  • Symbol: CUS10S30
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: cus10s30-etched.step / cus10s30-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cus10s30.step / cus10s30.glb are the bare package body.
