LCDP1521S
Dual line programmable transient voltage suppressor for SLIC protection-
Active
This device has been especially designed to protect 2 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 -VBATthrough the gate. Separated gates allow the SLICs to be supplied by two different voltages.

Datasheet
Key Features
- Dual line programmable transient voltage suppressor with separated gates
- Wide negative firing voltage range:VGn= -175 V max.
- Low dynamic switching voltages: VFPand VDGL
- Low gate triggering current: IGT= 5 mA max
- Peak pulse current: IPP= 40 A (5/310 μs)
- Holding current: IH= 150 mA min.
- Benefits
A Trisil™ is not subject to ageing and provides a fail safe mode in short circuit for a better protection. Trisils are used to help equipment to meet various standards such as UL1950, IEC 60950 / CSA C22.2, UL1459 and TIA-968-A (formerly FCC part 68). Trisils have UL94 V0 resin approved (Trisils are UL497B approved - file: E136224).
