CAD (KiCad official)

  • Symbol: BZM55C3V3-TR
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bzm55c3v3-tr-etched.step / bzm55c3v3-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzm55c3v3-tr.step / bzm55c3v3-tr.glb are the bare package body.
