BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS
TISP4SxxxBJ Overvoltage Protector Series
TISP4SxxxBJ Overview
These protection 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 onto 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 within rated limits through the device. The high crowbar holding current helps
prevent d.c. latchup as the diverted current subsides.
