Abstract
An apparatus and method for reducing and balancing the off-state capacitance of an overvoltage protection circuit utilizes one or more diode networks electrically connected in series with an overvoltage protection device. The overvoltage protection device is selected from the group consisting of a gas tube, an MOV, a transient voltage suppressor (TVS) diode and a TVS thyristor. Preferably, the overvoltage protection device is a solid-state overvoltage protector (SSOVP) having at least one thyristor. The diode network includes a plurality of diodes electrically connected in parallel and arranged with opposing polarities so that the circuit is bi-directional. Preferably, the diode network includes a first set of two or more stacked diodes electrically connected in parallel with a second set of two or more stacked diodes and arranged with opposing polarities, and the capacitance of the diode network is less than the capacitance of the thyristor.
