Abstract: An electrostatic discharge protection device is provided. In particular, the present disclosure relates to a semiconductor device that is particularly useful for ESD protection purposes. The semiconductor device further includes a second electronic component integrated on the semiconductor body and being spaced apart from the first electronic component, the second electronic component includes a first secondary region of the first charge type and a second secondary region of the second charge type arranged adjacent to the first secondary region, and the second secondary region is electrically connected to the second device terminal; and a first capacitive element, a first terminal thereof being electrically connected to the second primary region, and a second terminal thereof being electrically connected to the first secondary region.
