These devices have been especially designed to protect 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. These components present a very low gate triggering current (IGT) in order to reduce the current consumption on printed circuit board during the firing phase.
