Description

These devices are designed to limit overvoltages on the telephone line. 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 2-wire telecommunication equipment (e.g., between the Ring and Tip wires for telephones and modems). Combinations of

devices can be used for multi-point protection (e.g., 3-point protection between Ring, Tip and Ground).

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. 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.
