DW03D-B-S

Public Made by Adom

by adom

DOWO TVS, SOD-323. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: DW03D-B-S
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: dw03d-b-s-etched.step / dw03d-b-s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dw03d-b-s.step / dw03d-b-s.glb are the bare package body.
