CAD (KiCad official)

  • Symbol: ASMBJ24CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: asmbj24ca-etched.step / asmbj24ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); asmbj24ca.step / asmbj24ca.glb are the bare package body.
