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 being referenced to -VBAT through the gate. Separated gates allow the SLICs to be supplied by two different voltages.
