The SP4022 series integrates low capacitance steering diodes with one or two zener diodes for unidirectional or bidirectional protection, respectively, to protect against ESD and lightning induced surge events. These devices 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 and high surge capability make it ideal for protecting telecommunication ports such as xDSL and other high voltage, high speed legacy interfaces.  

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 (@ VR=0V)
  • Low leakage current
  • Unidirectional and Bidirectional configuration
  • Small SOD323 package fits 0805 footprints
  • AEC-Q101 qualified

Applications:

  • xDSL Interfaces
  • RS-232
  • RS-485
  • Power Ports
  • Security Equipment
  • Instrumentation
  • Medical Equipment
  • Computers and Peripherals
