CAD (KiCad official)

  • Symbol: ACDBC540-HF
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: acdbc540-hf-etched.step / acdbc540-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); acdbc540-hf.step / acdbc540-hf.glb are the bare package body.
