CAD (KiCad official)

  • Symbol: BAS321
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323(SC-90) (KiCad packages3D, STEP)
  • 3D model files: bas321-etched.step / bas321-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas321.step / bas321.glb are the bare package body.
