CAD (KiCad official)

  • Symbol: PESDNC9D3V3U
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: pesdnc9d3v3u-etched.step / pesdnc9d3v3u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesdnc9d3v3u.step / pesdnc9d3v3u.glb are the bare package body.

Provenance

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

  • Datasheet: Shanghai Prisemi Elec datasheet (6 pp, sha256 b3500a7e31474d3c, retrieved 2026-10-30, 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).
