CAD (KiCad official)

  • Symbol: ESD9M5.0ST5G
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: esd9m5-0st5g-etched.step / esd9m5-0st5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd9m5-0st5g.step / esd9m5-0st5g.glb are the bare package body.
