Patent ID: 7567416

Claim:
A transient voltage suppression device comprising: first and second dielectric layers each defining at least one variable impedance opening therein; at least one electrode extending between the first dielectric layer and including at least one gap that interrupts a conductive path through the at least one electrode, the at least one electrode being an electroformed foil formed independently of the first and second dielectric layers and integrally formed with the at least one gap, wherein the at least one electrode is sandwiched between the first and second dielectric layers; and the at least one variable impedance opening of the first and second dielectric layers being positioned proximate the at least one gap; third and fourth dielectric layers situated on the first and second dielectric layers, respectively, wherein the third and fourth layers close the at least one variable impedance opening in the first and second dielectric layers, respectively, and the first, second, third and fourth dielectric layers are secured to one another to form a chip structure; a variable impedance material situated in the at least one variable impedance opening of the first and second dielectric layers and substantially surrounding the at least one electrode from above and below; and surface mount terminations establishing a conductive path to the at least one electrode on either side of the at least one gap.
