  • Anti-lightning protection for telephone connection
    Patent number: 8687329
    Abstract: 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.
    Type: Grant
    Filed: June 6, 2011
    Date of Patent: April 1, 2014
    Assignee: STMicroelectronics (Tours) SAS

  • Protection of a communication line
    Patent number: 7746618
    Abstract: A circuit for protecting electronic equipment intended to be connected to at least one first conductor of a communication line, including, between this first conductor and a second conductor of the line or the ground to which is connected the equipment to be protected, at least one first branch including, in series, a first capacitive element and a first voltage-threshold triggering element, a first resistive element being connected in parallel with the first capacitive element.
