LCP1521S：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.
Positive overvoltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to -VBATthrough 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.
Key Features
- Programmable transient suppressor
- Wide negative firing voltage range:VGn
= -175 V max.
- Low dynamic switching voltages:VFP
and 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
- Trisil™ is not subject to ageing and provides a fail safe mode in short circuit for a better level of protection.
- Trisils are used to ensure equipment meets various standards such as UL60950, IEC 60950 / CSA C22.2, UL1459, TIA-968-A (formerly FCC part 68)
- Trisils have UL94 V0 approved resin (Trisils are UL497B approved [file: E136224]).
