CAD (KiCad official)

  • Symbol: KSMAJ16A-E3
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: ksmaj16a-e3-etched.step / ksmaj16a-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ksmaj16a-e3.step / ksmaj16a-e3.glb are the bare package body.
