Abstract
A varistor device for voltage-surge-protecting an electronic circuit at a cryogenic temperature comprises an electric lead composed of a superinsulator material, and electrical contact elements. The electrical contact elements are for connecting different positions along the electric lead to the electronic circuit. The electrical contact elements are in electric contact with the electric lead at the different positions along the electric lead. The electric lead is adapted to provide a superinsulating state or a cooper-pair insulating state at the cryogenic temperature, and to provide a non-linear resistance between the different positions at the cryogenic temperature.
