DESCRIPTION
TheLCDP1511Disaduallineprotectorwhichprotects subscriber line interface circuits (SLIC)
againsttransientovervoltages.
Positiveovervoltagesareclamped with diodes towards GND, while negative overvoltages are suppressed by thyristors connected to GND. The
breakdownvoltage of the thyristorsis determined
by the voltageapplied to the gate, generally -V
