AQ4021 Series - 2.5pF, 25A Discrete TVS Diode

The AQ4021 components integrate 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 components can safely absorb up to 25A 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 make it ideal for protecting telecommunication ports such as Ethernet and other high speed data interfaces.

Features:

  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC 61000-4-4, 40A (5/50ns)
  • Lightning, IEC 61000-4-5 2nd edition, 25A (tP=8/20μs)
  • Low capacitance of 2.5pF(@ VR=0V)
  • Low leakage current
  • Unidirectional and Bidirectional configuration
  • Small SOD323 package fits 0805 footprints
  • AEC-Q101 qualified
  • Halogen free, Lead free and RoHS compliant
  • Moisture Sensitivity Level (MSL -1)

Applications:

  • 10/100/1000 Ethernet
  • T1/E1/T3/E3
  • USB 1.1/2.0
  • Power Ports
  • Computers and Peripherals
  • Instrumentation
  • Medical Equipment
