CAD (KiCad official)

  • Symbol: KPESD3V3S1BA-N
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: kpesd3v3s1ba-n-etched.step / kpesd3v3s1ba-n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kpesd3v3s1ba-n.step / kpesd3v3s1ba-n.glb are the bare package body.

Provenance

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

  • Datasheet: KUU datasheet (5 pp, sha256 d7aa37d50c2840f4, retrieved 2026-10-16, 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).
