The unidirectional AQxx-01FTG series is designed to replace multilayer varistors (MLVs) in electronic equipment for low speed and DC applications. It will protect any sensitive
equipment from damage due to electrostatic discharge (ESD) and other transient events.

The AQxx-01FTG series can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 30A (AQ05) of 8/20μs induced surge current (IEC 61000-4-5) with very low clamping voltages.

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, 30A (tP=8/20μs, AQ05)
  • Low clamping voltage
  • Low leakage current
  • Small SOD323 package fits 0805 footprints
  • AEC-Q101 qualified
  • Halogen free, Lead free and RoHS compliant
  • Moisture Sensitivity Level (MSL -1)

Applications:

  • Switches / Buttons
  • Test Equipment / Instrumentation
  • Point-of-Sale Terminals
  • Medical Equipment
  • Notebooks / Desktops / Servers
  • Computer Peripherals
  • Automotive Electronics
