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 protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping un-
til 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 helps prevent d.c. latchup
as the diverted current subsides.
Please contact your Bourns representative if the protection voltage you require is not listed.
