CAD (KiCad official)

  • Symbol: B5818W
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: b5818w-etched.step / b5818w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b5818w.step / b5818w.glb are the bare package body.

Provenance

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

  • Datasheet: hongjiacheng datasheet (3 pp, sha256 fffa38bc81b3058b, retrieved 2026-11-04, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary cathode-band convention (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
