CAD (KiCad official)

  • Symbol: TCMM5Z6V2
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: tcmm5z6v2-etched.step / tcmm5z6v2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tcmm5z6v2.step / tcmm5z6v2.glb are the bare package body.
