1. A printed circuit board, comprising:

  • at least one conductor;

    a voltage switchable dielectric material (VSDM) layer applied to the at least one conductor;

    an electronic component having at least one lead and disposed on the VSDM layer, wherein the at least one lead is electrically coupled to the VSDM layer;

    a via; and

    a conductive pad connected to the conductor by the via,wherein the VSDM layer comprises an active volume defined by a gap between the at least one lead and the conductive pad, wherein the active volume to pass current through to a ground during an overvoltage event.
