Description
LCP1521S/LCP152DEE ASD (Application Specific Devices) Programmable transient voltage suppressor for SLIC protection .
These devices have been especially designed to protect new high voltage, as well as classical SLICs, against transient overvoltages.
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
Applications
* such as the fiber in the loop, the WLL, the remote central office. In this case, the operating voltages are smaller than in the classical system. This makes the high voltage SLICs particularly suitable. The schematics of Figure 7. give the most frequent topology used for these applications. Figure 7
