CAD (KiCad official)

  • Symbol: SMAJ36CA-Q
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC (KiCad packages3D, STEP)
  • 3D model files: smaj36ca-q-etched.step / smaj36ca-q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj36ca-q.step / smaj36ca-q.glb are the bare package body.
