Abstract

A two-dimensional silicon controlled rectifier (2DSCR) having the anode and cathode forming a checkerboard pattern. Such a pattern maximizes the anode to cathode contact length (the active area) within a given SCR area, i.e., effectively increasing the SCR width. Increasing the physical SCR area, increases the current handling capabilities of the SCR.
