Abstract
The invention relates to an integrated circuit having a semiconductor component () comprising a first p-type region () and a first n-type region () adjoining the first p-type region (), which together form a first pn junction having a breakdown voltage. According to the invention, a further n-type region adjoining the first p-type region or a further p-type region () adjoining the first n-type region () is provided, the first p-type or n-type region () and the further n-type or p-type region () adjoining the latter together forming a further pn junction having a further breakdown voltage, the first pn junction and the further pn junction being connected or connectable to one another in such a way that, in the case of an overloading of the semiconductor component, on account of a current loading of the first pn junction, first of all the further pn junction breaks down.
