1.5SMC27C

Public Made by Adom

by adom

Littelfuse TVS, 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: 1.5SMC27C
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB (KiCad packages3D, STEP)
  • 3D model files: 1-5smc27c-etched.step / 1-5smc27c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1-5smc27c.step / 1-5smc27c.glb are the bare package body.

Provenance

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