Abstract

A circuit arrangement for protection against electrostatic discharges comprises a diverting element, which is connected between a first and a second terminal and has a control input, via which the diverting element can be controlled into the conducting state. Moreover, trigger elements are provided, which have a trigger output for outputting a trigger signal in a manner dependent on a voltage between the first and the second terminal. The circuit arrangement furthermore comprises at least one amplifier unit, which is coupled to one of the trigger outputs on the input side and to the control input on the output side.
