LCP1521DEE

LCP1521S/LCP152DEE ASD (Application Specific Devices) Programmable transient voltage suppressor for SLIC protection 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 min Low space consuming package SO-8 LCP1521S QFN 3x3 6 leads LCP152DEE Order codes Part Number LCP1521S LCP1521SRL LCP152DEERL Marking CP152S CP152S LCP152 Description 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 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. Figure 1.

Trisils are used to ensure equipment meets various standards such as UL60950, IEC950 / CSA C22.2, UL1459 and FCC part 68. Trisils have UL94 V0 approved resin (Trisils are UL497B approved [file: E136224]). RING RING Figure 2. LCP152DEE Functional diagram ...
