  • Dedicated to telecommunication equipment protection, these devices provide a triple bidirectional protection function.

    They ensure the same protection capability with the same breakdown voltage both in longitudinal mode and transversal mode.
    A particular attention has been given to the internal wire bonding. The “4-point” configuration ensures a reliable protection, eliminating overvoltages introduced by the parasitic inductances of the wiring (Ldi/dt), especially for very fast transient overvoltages.
    Dynamic characteristics have been defined for several types of surges to meet the SLIC maximum ratings.

    Key Features

    • bidirectional crowbar protection between TIP and GND, RING and GND and between TIP and RING
    • peak pulse current:IPP= 30 A for 10/1000 μs surge
    • holding current: IH= 150 mA
    • Complies with Bellcore standard
      • TR-NWT-001089-Core, (second level) with line series resistors:
        • 10/1000 μs, 1000 V
        • 2/10 μs, 2500 V (first level)
        • 2/10 μs, 5000 V
