Description
These devices are designed to limit overvoltages on the telephone and data lines. Overvoltages are normally caused by a.c. power system or
lightning flash disturbances which are induced or conducted on to the telephone line. A single device provides 2-point protection and is
typically used for the protection of ISDN power supply feeds. Two devices, one for the Ring output and the other for the Tip output, will provide
protection for single supply analogue SLICs. A combination of three devices will give a low capacitance protector network for the 3-point
protection of ISDN lines.
The protector consists of a voltage-triggered unidirectional thyristor with an anti-parallel diode. Negative overvoltages are initially clipped by
breakdown clamping until the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. This low-
voltage on state causes the current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current
prevents d.c. latchup as the diverted current subsides. Positive overvoltages are limited by the conduction of the anti-parallel diode.
