Abstract
A structure for protection against electrostatic surges having two input terminals and two output terminals. The output terminals of the structure are connected to the inputs of a circuit to be protected. A first input terminal is connected to a first output terminal via an impedance. The second input terminal is connected to the second output terminal. The input terminals are interconnected by a first avalanche diode. The output terminals are interconnected by a second avalanche diode having the same biasing as the first avalanche diode.
