Abstract: A surge protector (10) for protecting telecommunications related equipment and other associated sensitive electrical components from over-voltage transient occurring on tip/ring conductors (A-H) of telecommunication lines coupled thereto includes a printed circuit board (14) and a plurality of surge protection circuits (12a-12d) being mounted on the printed circuit board (14). Each of the plurality of surge protection circuits (12a) includes a first set of steering diodes (D1, D2, D17, D18) and a second set of steering diodes (D3, D4, D19, D20). A common transient voltage clamping device (D33) has a first end connected to a first conductor lead (16) and a second end connected to a second conductor lead (18) so as to be shared by the plurality of surge protection circuits (12a-12d). A common pair of series-connected rectifier diodes (D34, D35) has a first end also connected to the first conductor lead (16) and a second end also connected to the second conductor lead (18) so as to be shared by the plurality of surge protection circuits (12a-12d).
