The SP3312T integrates 4 channels (2 differential pair) of low capacitance diodes to protect sensitive I/O pins against lightning induced surge events and ESD. This robust device can safely absorb up to 15A per IEC61000-4-5 (tp=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC61000-4-2 international standard. The low loading capacitance makes the SP3312T ideal for protecting high-speed signal pins.

Features:

  • ESD IEC61000-4-2,±30kV contact, ±30kV air
  • EFT, IEC61000-4-4, 40A (5/50ns)
  • Lightning, IEC61000-4-5, 15A (tP=8/20μs)
  • Low capacitance of 1.3pF (TYP) per I/O
  • Low leakage current of 0.01μA (TYP) at 3.3V
  • Low variation in capacitance vs. bias voltage: 0.3pF Typical(VR=0 to 2.5V) 

Application:

  • 10/100/1000 Ethernet
  • Integrated magnetics/RJ45 connectors
  • LAN/WAN Equipment
  • Security Cameras
  • Industrial Controls
  • Notebook & Desktop Computers
