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.

Benefits
TRISILs™ are not subject to ageing and provide 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, IEC950 / CSA C22.2, UL1459 and FCC part 68. Trisils have UL94 V0 approved resin (Trisils are UL497B approved [file: E136224]).
