Abstract

The surface mountable electrical device provides utilizes polymer composite materials to protect electronic components against electrical overstress transients. The device includes a first substrate having an electrode formed thereon. A portion of the electrode forms an electrical connector which projects outwardly from the substrate. A second substrate has a electrode formed on a surface thereof. A portion of the electrode on the second substrate forms a well or cavity. A voltage variable material is disposed within the cavity formed in the electrode on the second substrate. The two substrates are laminated together such that the electrical connector extends into the voltage variable material disposed within the cavity. Outer terminations adapted to be connected to an electrical circuit are formed on the outer surfaces of the substrates and are electrically connected to each respective electrode.
