These devices have been especially designed to protect new high voltage, as well as classical SLICs, against transient overvoltages.
www.DataSheet4U.com Positive overvoltages are clamped by 2 diodes.
Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to -VBAT t
LCP1521DEE 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 = 5 mA max Peak pulse current: IPP = 30 A (10/1000 µs) Holding current: IH = 150 mA m
