Abstract

In the case of an electronic apparatus (1), a protective circuit (10) for positive and negative voltage spikes is provided, which circuit includes two diodes (12, 13). The first diode (12), polarized in the forward direction, is arranged in the positive branch of the voltage supply. The second diode (13), polarized in the reverse direction, is connected, on the one hand, to the cathode connection of the first diode (12) and, on the other hand, to the ground connection.
