KSMCJ5.0A-E3-57T

Public Made by Adom

by adom

KUU TVS, SMC(DO-214AB). Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: KSMCJ5.0A-E3-57T
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: ksmcj5-0a-e3-57t-etched.step / ksmcj5-0a-e3-57t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ksmcj5-0a-e3-57t.step / ksmcj5-0a-e3-57t.glb are the bare package body.

Provenance

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