Claim:
1. A device of protection against transient electrical overvoltages, comprising: two voltage-limiting passive components, disconnectors sensitive to a state of the components and adapted to individually disconnect each end of life component therefrom, wherein the components are joined in parallel between a first and a second terminal of the device, wherein a reference voltage of the first component is inferior to a reference voltage of the second component, and wherein a ratio of the reference voltages is inferior to 2 and wherein, for a voltage applied between the first terminal and the second terminal exceeding the reference voltage of the first component, the current flowing through the first component is greater than the current flowing through the second component and the difference between the current flowing through the first component and the current flowing through the second component is increasing when the voltage applied between the first terminal and the second terminal is increasing.
