s s s s s s Dual line programmable transient voltage suppressor Wide negative firing voltage range: VMGL = -150 V max. Low dynamic switching voltages: VFP and VDGL .

such as the fiber in the loop, the WLL, the remote central office. In this case, the operating voltages are smaller than.

This device has been especially designed to protect 2 new high voltage, as well as classical SLICs, against transient overvoltages. Positive overvoltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage.
