CAD (KiCad official)

  • Symbol: 1N5819HW-MS
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: 1n5819hw-ms-etched.step / 1n5819hw-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1n5819hw-ms.step / 1n5819hw-ms.glb are the bare package body.
