CAD (KiCad official)

  • Symbol: BNPESD3V3U1UA
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bnpesd3v3u1ua-etched.step / bnpesd3v3u1ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bnpesd3v3u1ua.step / bnpesd3v3u1ua.glb are the bare package body.
