CAD (KiCad official)

  • Symbol: LESD9D12T5G
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: lesd9d12t5g-etched.step / lesd9d12t5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lesd9d12t5g.step / lesd9d12t5g.glb are the bare package body.
