CAD (KiCad official)

  • Symbol: 1N4148WS-HF
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: 1n4148ws-hf-etched.step / 1n4148ws-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1n4148ws-hf.step / 1n4148ws-hf.glb are the bare package body.
