This devices are designed to limit overvoltages on telecom lines. The device is primarily designed to address GR-1089-CORE compliance on data transmission lines with d.c. power feeding. When overvoltage protection is applied to transformer coupled lines from the transformer center tap to ground, the total ground return current can be 200 A, 10/1000 and 1000 A, 2/10. The high 150 mA holding current is set above common d.c. feed system levels to allow the device to reset following a disturbance.These devices allow signal voltages, without clipping, up to the maximum off-state voltage value, VDRM. Voltages above VDRM are limited and will not exceed the breakover voltage, VBO, level. If sufficient current flows due to the overvoltage, the device switches into a low voltage on-state condition, which diverts the current from the overvoltage through the device. When the diverted current falls below the holding current, level the devices switches off and restores normal system operation.
