The AQxx-02HTG Series TVS Diode Array is designed to protect sensitive equipment from damage due to electrostatic discharge (ESD), electrical fast transients (EFT), and lightning induced surges.

This AQxx-02HTG series can safely absorb repetitive ESD strikes of ±30 kV (contact and air discharge as defined in IEC 61000-4-2) without any performance degradation. Additionally, the AQ05 can safely conduct a 33A 8/20 surge event as defined in IEC 61000-4-5 2nd edition at low voltage clamping levels.


  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC 61000-4-4, 50A (5/50ns)
  • LLightning, 33A (8/20 as defined in IEC 61000-4-5 2nd edition) for the AQ05
  • Working voltages: 5V, 12V, 15V, 24V and 36V
  • Low clamping voltage
