CAD (KiCad official)

  • Symbol: Z1SMA24
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: z1sma24-etched.step / z1sma24-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); z1sma24.step / z1sma24.glb are the bare package body.
