CAD (KiCad official)

  • Symbol: ESDA051-1JY
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: esda051-1jy-etched.step / esda051-1jy-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esda051-1jy.step / esda051-1jy.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (11 pp, sha256 ba06efd6d3db371f, retrieved 2026-11-04, tier: manufacturer)
  • 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).
