Abstract
An ESD protection device for protecting a circuit against electrostatic discharges. The ESD protection device having a series circuit of N diodes, each diode comprising an anode and a cathode. The series circuit being connected between two supply potentials. The diodes being so arranged that a spatial distance between the anode of a first diode and the cathode of an Nth diode of the series circuit is less than a maximum distance between the anode or cathode of a first spatially outer diode of the series circuit and the anode or cathode of a second spatially outer diode of the series circuit.
