摘要： A surge protector for protecting telecommunications related equipment and other associated sensitive electrical components from over-voltage transient occurring on tip/ring conductors of telecommunication lines coupled thereto includes a printed circuit board and a plurality of surge protection circuits being mounted on the printed circuit board. Each of the plurality of surge protection circuits includes a first set of steering diodes and a second set of steering diodes. A common transient voltage clamping device has a first end connected to a first conductor lead and a second end connected to a second conductor lead so as to be shared by the plurality of surge protection circuits. A common pair of series-connected rectifier diodes has a first end also connected to the first conductor lead and a second end also connected to the second conductor lead so as to be shared by the plurality of surge protection circuits.
