CAD (KiCad official)

  • Symbol: BSDFN2C181U
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2L (KiCad packages3D, STEP)
  • 3D model files: bsdfn2c181u-etched.step / bsdfn2c181u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsdfn2c181u.step / bsdfn2c181u.glb are the bare package body.
