CAD (KiCad official)

  • Symbol: SK310B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: sk310b-etched.step / sk310b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sk310b.step / sk310b.glb are the bare package body.
