Abstract
A substrate device includes a layer of non-linear resistive transient protective material and a plurality of conductive elements that form part of a conductive layer. The conductive elements include a pair of electrodes that are spaced by a gap, but which electrically interconnect when the transient protective material is conductive. The substrate includes features to linearize a transient electrical path that is formed across the gap.
