CAD (KiCad official)

  • Symbol: ZP-SMAJ70CA
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: zp-smaj70ca-etched.step / zp-smaj70ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); zp-smaj70ca.step / zp-smaj70ca.glb are the bare package body.
