Abstract
Methods of protecting against a surge voltage and apparatus for performing the same. One embodiment of the invention is directed to a circuit to protect a device from a surge voltage. The circuit is connected between the device and first and second nodes to which the surge voltage may be applied. A charge storage device is connected between third and fourth nodes and the device is operatively connected to the third node and a fifth node. The circuit comprises a first overvoltage protection device coupled between the fourth node and a fifth node, the fourth and fifth nodes being operatively connected to the first and second nodes, respectively, and a second overvoltage protection device coupled between the third node and the fifth node. A voltage between the third and fifth nodes during the surge voltage is substantially less than a switching voltage of the second overvoltage protection device for at least a portion of the duration of the surge voltage.
