  • This device has been 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.
    This component presents a very low gate triggering current (IGT) to reduce the current consumption on printed circuit boards during the firing phase.

    Key Features

    • dual-line programmable transient voltage suppressor
    • wide negative firing voltage range
    • VMGL= -150 V max.
    • low dynamic switching voltages: VFPand VDGL
    • low gate triggering current: IGT= 5 mA max.
    • peak pulse current: IPP= 20 A (10/1000 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 better protection.
      • Trisils are used to help equipment meet various standards such as UL1950, IEC 950 / CSA C22.2, UL1459 and FCC part68.
      • Trisils have UL94 V0 approved resin.
      • Trisils are UL497B approved (file: E136224).
