Abstract
The protection device comprises a MOS transistor formed on the substrate of the integrated circuit and connected between a circuit pad and a reference terminal of the integrated circuit. A thyristor formed on the substrate is connected between the pad and the reference terminal. The control electrode of this thyristor consists of a region of the substrate in such a way that the thyristor can be triggerred by a current of charge carriers produced in the substrate by avalanche when a voltage rise occurs between the substrate and the drain of the MOS transistor.
