Dual line programmable transient voltage suppressor for SLIC protection

This device has been especially 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 -VBAT through the gate. Separated gates allow the SLICs to be supplied by two different voltages.

Key Features

  • Dual line programmable transient voltage suppressor with separated gates
  • 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.
