CAD (KiCad official)

  • Symbol: 1N4148M9
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: 1n4148m9-etched.step / 1n4148m9-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1n4148m9.step / 1n4148m9.glb are the bare package body.

Provenance

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

  • Datasheet: amsem datasheet (3 pp, sha256 bf2153b94f8c7269, retrieved 2026-10-26, 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).
