Description
These medium-voltage dual bidirectional thyristor protectors are designed to protect ground backed ringing central office, access and
customer premise equipment against overvoltages caused by lightning and a.c. power disturbances. Offered in three voltage variants to meet
battery and protection requirements, they are guaranteed to suppress and withstand the listed international lightning surges in both polarities.
Overvoltages are initially clipped by breakdown clamping until the voltage rises to the breakover level, which causes the device to switch. The
high crowbar holding current helps prevent d.c. latchup as the current subsides.
These monolithic protection devices are fabricated in ion-implanted planar structures to ensure precise and matched breakover control and
are virtually transparent to the system in normal operation.
