CAD (KiCad official)

  • Symbol: BZ-SMF24A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: bz-smf24a-etched.step / bz-smf24a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bz-smf24a.step / bz-smf24a.glb are the bare package body.
