High Power TVS for Ethernet Interfaces

Add to Watch List

RailClamp® TVS diodes are specifically designed to protect sensitive components which are connected to
high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE
(cable discharge events), and EFT (electrical fast transients).


  • Transient protection for high-speed data lines to
  • IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact)
  • IEC 61000-4-4 (EFT) 40A (5/50ns)
  • IEC 61000-4-5 (Lightning) 40A (8/20μs)
  • Array of surge rated diodes with internal TVS Diode
  • Qualified to AEC-Q100 Grade 1 (-45 to +125oC)
  • Protects up to eight lines
  • Low capacitance for high-speed interfaces
  • Low variation in capacitance vs. bias voltage
  • Low clamping voltage
  • Low operating voltage: 3.3V
  • Solid-state silicon-avalanche technology


  • 10/100/1000 Ethernet
  • Automotive
  • Central Office Equipment
  • LVDS Interfaces
  • MagJacks / Integrated Magnetics
  • Notebooks / Desktops / Servers


  • SLP3020N10
