CAD (KiCad official)

  • Symbol: 1N4148WSF-7
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: 1n4148wsf-7-etched.step / 1n4148wsf-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1n4148wsf-7.step / 1n4148wsf-7.glb are the bare package body.
