DESCRIPTION

This device has 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.

FEATURES

■ Dual programmable transient suppressor

■ Wide negative firing voltage range: VMGL= -150 V max.

■ Low dynamic switching voltages: VFPand VDGL

■ Low gate triggering current: IGT=5mAmax

■ Peak pulse current: IPP= 30 A (10/1000µs)

■ Holding current: IH= 150 mA min
