ANTI-LIGHTNING PROTECTION FOR TELEPHONE CONNECTION |
摘要 |
A structure for protecting a circuit connected to first and second rails of a telephone connection against overvoltages, including: first and second diodes in anti-series between the first and second rails; a first capacitor in parallel with a first resistor between a first node common to the first and second diodes and a low voltage reference node; and a protection element capable of removing fast overvoltages between any of the rails and the low reference voltage node when these overvoltages exceed a first threshold associated with the voltage of the first node.
