An overvoltage protector bridge circuit for protecting telecommunications equipment against voltage surges on transmission lines utilizes an overvoltage protection device in a bridge circuit having multiple diodes arranged in series or in parallel on each leg of the circuit. The overvoltage protection device conducts when it reaches a threshold voltage potential. The overvoltage protection device is electrically connected between a pair of connection nodes in the bridge circuit. The bridge circuit is made up of multiple diodes arranged along each of the legs of the circuit, which extend between the tip line and the ring line and the connection nodes. At least two diodes are arranged in series or in parallel along each leg of the bridge circuit to steer the excess voltage on the tip line or the ring line, or both, through the overvoltage protection device to ground. The use of multiple diodes on each leg of the bridge circuit reduces the effective off-state capacitance of the overvoltage protection device, thereby permitting the bridge circuit to be utilized for high frequency transmission line applications, and increases the overall surge current handling capability of the bridge circuit.
