CAD (KiCad official)

  • Symbol: RB521BS-30-MS
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: SOD-882 (KiCad packages3D, STEP)
  • 3D model files: rb521bs-30-ms-etched.step / rb521bs-30-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rb521bs-30-ms.step / rb521bs-30-ms.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
