PROGRAMMABLE TRANSIENT VOLTAGE SUPPRESSOR FOR SLIC PROTECTION
Application Specific Discretes A.S.D.TM
Features
Dual programmable transient suppressor Wide negative firing voltage range: VMGL = -150 V max. Low dynamic switching voltages: VFP and VDGL Low gate triggering current: IGT = 2 mA max Peak pulse current: IPP = 30 A (10/1000 µs) Holding current: IH = 150 mA
SO-8 DESCRIPTION This device has been especially designed to protect new high voltage, as well as classical SLICs, against transient overvoltages. Positive overvoltages are clipped with 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to -VBAT through the gate....
