LCDP1521:Dual protection for single voltage SLICs

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: VFP and 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).
