CAD (KiCad official)

  • Symbol: KSJD12A28L01
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: ksjd12a28l01-etched.step / ksjd12a28l01-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ksjd12a28l01.step / ksjd12a28l01.glb are the bare package body.
