component
SLD33-018
Public Made by Adomby adom
Littelfuse ESD And Surge Protection (TVS/ESD), P600. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.
Made with kicad-footprint-generator 10.0 · KiCad file format 20260206
