ABSTRACT:
A spark gap device for protecting an integrated circuit. The spark gap device includes a first node for receiving an input signal and a second node to be protected. A first conductive layer is conductively interfaced to the first node and the second node and disposed therebetween. A second conductive layer is connected to a sink voltage and separated from the first conductive layer by an insulating layer of a predetermined thickness. A portion of the first conductive layer is disposed proximate to the second conductive layer and not overlying the second conductive layer, such that a gap is formed therebetween and the gap having a dimension that is greater than the thickness of the insulating layer.
