CAD (KiCad official)

  • Symbol: MM1W39
  • Footprint: Diode_SMD:D_SOD-123
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1w39-etched.step / mm1w39-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1w39.step / mm1w39.glb are the bare package body.

Provenance

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

  • Datasheet: Shandong Jingdao Microelectronics datasheet (3 pp, sha256 013135782e49243c, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
