CAD (KiCad official)

  • Symbol: B240A-E3
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: b240a-e3-etched.step / b240a-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b240a-e3.step / b240a-e3.glb are the bare package body.
