Abstract
An integrated component for protecting against temporary power surges comprises a first conductive lead and a second conductive lead, each of which mounted on an electrical circuit; a gas discharge tube; a thermally protected varistor and a thermal fuse. The thermally protected varistor comprises a varistor body, a first varistor electrode and a second varistor electrode that are positioned on either side of the varistor body. The varistor body rises in temperature when the voltage imposed between the first and the second varistor electrodes exceeds a voltage threshold. An electrical connection is made via the thermal fuse.
