Zusammenfassung:PURPOSE: A static electricity discharge protecting device is provided to adjust a trigger voltage in consideration of the operating voltage and a breakdown voltage of an internal circuit device. CONSTITUTION: A first conductive area(140) and a second conductive area are formed on a substrate(110). A diffusion layer is formed on the first conductive area and electrically connected to an anode. The diffusion layer is formed on second conductive areas(120,130) and electrically connected to a cathode. A second conductive doped area is located in the lower part of the second conductive area.
