CAD (KiCad official)

  • Symbol: SMAJ17CA-E3
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: smaj17ca-e3-etched.step / smaj17ca-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj17ca-e3.step / smaj17ca-e3.glb are the bare package body.
