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 -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.

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:
    • 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 UL60950, 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)
