The SP3384NUTG Series can protect up to four channels against up to 15A (IEC 61000-4- 5 2nd edition) and up to ±30kV ESD (IEC 61000-4-2) and is available in a compact μDFN package. The combination of low capacitance and low clamping voltage make the SP3384NUTG a robust protection solution for 2.5G/5G/10G Ethernet high-speed data interfaces without signal degradation, resulting in high reliability for a variety of applications.


  • Low capacitance (0.5pF per I/O) and low clamping voltage (4V@Ipp=1A)  
  • Compact μDFN packaging (3.0 x 2.0mm)
  • Provides protection for two differential data pairs (4 channels) against up to 15A


  • More robust device against electrical threats preserves signal integrity and minimizes data loss 
  • Optimized for protection of high-speed differential data lines
  • Exceeds the maximum IEC standards requirement for ESD protection, ensuring product reliability 

Markets/ Applications:

  • 2.5G/5G/10G Ethernet, WAN/LAN Equipment, 5G Wireless Backhaul
  • LVDS Interfaces, Integrated Magnetics
  • Desktops, Servers and Notebooks
