ABSTRACT:
A two-terminal current limiting component, includes a substrate of a first conductivity type; separated wells of the second conductivity type; a first annular region of the first conductivity type in each well; a second annular region of the first conductivity type having a low doping level between the periphery of each first annular region and the periphery of each well; an insulating layer over the second annular region and the surface portions of the substrate; a first metallization coating the upper surface of the component; and a second metallization coating the lower surface of the component.
