Description

These devices are designed to limit overvoltages on digital telecommunication 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 transformer windings and low voltage electronics.

The protector consists of a symmetrical voltage-triggered bidirectional thyristor. 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 condition. This low-voltage on state

causes the current resulting from the overvoltage to be safely diverted through the device. The device switches off when the diverted current

falls below the holding current value.
