The SP4031 hybrid protector offers both overcurrent and differential only overvoltage protection for applications such as 10/100/1000BaseT ports. Compliant with the newest standards of overvoltage per industry standard ITU-T K.21. Tested to basic tests levels 2.5kV overvoltage. Flow-through package layout allows PCB trace routing directly through the SP4031 without changing pitch dimensions, thus having less impact on normal signal high frequency components.

During a prolonged overvoltage event such as a power fault, this component will present a high impedance. The high impedance state will reset once the power fault event has ended. During a fast transient event, the component will clamp, thus protecting any downstream chipsets.

These components can safely absorb up to 35A per IEC 61000-4-5 2nd edition (tP=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC 61000-4-2 International Standard. The low loading capacitance and high surge capability makes the SP4031 ideal for protecting telecommunication ports such as Ethernet and other high speed data interfaces.

Features & Benefits:

  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC 61000-4-4, 40A (5/50ns)
  • Lightning, 35A (8/20 as defined in IEC 61000-4-5 2nd edition)
  • Low capacitance of 2.5pF (@VR=0V)
  • Moisture Sensitivity Level (MSL -1)
  • Lead free and RoHS compliant
  • This SP4031 hybrid component provides a tested and proved protection solution for high-speed interfaces such as 10/100/1000BaseT applications
  • Low parasitic capacitance
  • Low operating voltage (<3.3 V)
  • Low breakdown voltage (>3.5V)

Applications:

  • 10/100/1000BaseT Ethernet
  • ITU K.21 Basic level compliance
  • ADSL/VDSL/G.fast modem
  • Industrial Ethernet
