CAD (KiCad official)

  • Symbol: SZMM5Z11VT5GF
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: szmm5z11vt5gf-etched.step / szmm5z11vt5gf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); szmm5z11vt5gf.step / szmm5z11vt5gf.glb are the bare package body.
