CAD (KiCad official)

  • Symbol: 5.0SMDJ48A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: 5-0smdj48a-etched.step / 5-0smdj48a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 5-0smdj48a.step / 5-0smdj48a.glb are the bare package body.
