Description
This device is 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 device consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping.
If sufficient current is available from the overvoltage, the breakdown voltage will rise to the breakover level, which causes the device to
switch into a low-voltage on-state condition. This switching action removes the high-voltage stress from the following circuitry and causes
the current resulting from the overvoltage to be safely diverted through the device. The high holding (switch off) current helps prevent
d.c. latchup as the diverted current subsides. This device is designed to voltage limit and withstand the listed lightning surges in both
polarities.
