CAD (KiCad official)

  • Symbol: B140S1F-7
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123F (KiCad packages3D, STEP)
  • 3D model files: b140s1f-7-etched.step / b140s1f-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b140s1f-7.step / b140s1f-7.glb are the bare package body.
