Sales Briefcase
  • 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)
