A miniaturized Category 5 protection device for protecting telecommunication related equipment and the like from power and transient surges includes a plurality of sets of line-pair wires. Voltage suppressor circuitry is interconnected between each of the plurality of sets of line-pair wires. One of the plurality of sets of line-pair wires has a first input tip terminal, a first input ring terminal, a first output ring terminal, and a first output ring terminal. Another one of the plurality of sets of line-pair wires has a second input tip terminal, a second input ring terminal, a second output tip terminal, and a second output ring terminal. Variable capacitance circuitry is coupled between the first input tip terminal and the second input tip terminal, the first input ring terminal and the second input ring terminal, the first output tip terminal and the second output ring terminal, and the first output ring terminal and the second output tip terminal for preventing crosstalk between the one of the plurality of sets of line-pair wires and the other one of the plurality of sets of line-pair wires.
