CAD (KiCad official)

  • Symbol: SMAJ20CAHE3_A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: smaj20cahe3-a-etched.step / smaj20cahe3-a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj20cahe3-a.step / smaj20cahe3-a.glb are the bare package body.
