CAD (KiCad official)

  • Symbol: KSMCJ48CA-E3-57T
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: ksmcj48ca-e3-57t-etched.step / ksmcj48ca-e3-57t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ksmcj48ca-e3-57t.step / ksmcj48ca-e3-57t.glb are the bare package body.

Provenance

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

  • Datasheet: KUU datasheet (6 pp, sha256 21bcf911832a226d, retrieved 2026-10-15, 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.
