The SR70 consists of four, low capacitance, rail-to-rail diodes that provide protection against ESD and lightning surge events. These robust diodes can safely absorb up to 40A (tP=8/20μs) and repetitive ESD strikes at the maximum level (Level 4) specified in the IEC 61000-4-2 international standard without performance degradation.

Its low loading capacitance makes it ideal for protecting high-speed data lines such as VDSL and VDSL2.

Features & Benefits:

  • ESD, IEC61000-4-2 , ±30kV contact discharge, ±30kV air discharge
  • EFT, IEC61000-4-4, 80A (tP=5/50ns)
  • Lightning protection, IEC61000-4-5, 40A (tP=8/20μs)
  • Low capacitance of 2.0pF (TYP) per I/O
  • Low clamp voltage
  • Small SOT143 (JEDEC TO-253) packaging

Applications:

  • xDSL Lines
  • Video Lines
  • Customer Premises Equipment
  • 10/100/1000 Ethernet
