CAD (KiCad official)

  • Symbol: SMAJ5.0CA-JSM
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: smaj5-0ca-jsm-etched.step / smaj5-0ca-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj5-0ca-jsm.step / smaj5-0ca-jsm.glb are the bare package body.
