1. A varistor having a rectangular configuration defining first and second opposing end surfaces offset in a lengthwise direction, the varistor comprising:
a first terminal adjacent the first opposing end surface;
a second terminal adjacent the second opposing end surface;
an active electrode layer comprising a first electrode electrically connected with the first terminal and a second electrode electrically connected with the second terminal, the first electrode spaced apart from the second electrode in the lengthwise direction to form an active electrode end gap; and
a floating electrode layer comprising a floating electrode, the floating electrode layer spaced apart from the active electrode layer in a height-wise direction to form a floating electrode gap;
wherein the active electrode end gap ranges from about 100 microns to about 1000 microns and the floating electrode gap ranges from about 15 microns to about 300 microns.
