THBT15011:Tripolar overvoltage protection for telecom line

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
    • 2/10 μs, 2500 V (first level)
    • 2/10 μs, 5000 V
