CAD (KiCad official)

  • Symbol: SMCJ8.5CA
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smcj8-5ca-etched.step / smcj8-5ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj8-5ca.step / smcj8-5ca.glb are the bare package body.

Provenance

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

  • Datasheet: Taisko datasheet (8 pp, sha256 bb76d9c11f3fc36a, retrieved 2026-10-22, 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).
