The AQHVxx-01LTG series is designed to provide an option for very fast acting, high performance over-voltage protection components. This series is ideally suited for power interfaces, passenger charging interfaces, and well as LED lighting modules, and low speed I/Os. It will protect sensitive equipment from damage due to electrostatic discharge (ESD) and other overvoltage transients. 

It can safely absorb repetitive ESD strikes above the maximum level of the IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation and safely conduct up to 10A (AQHV12) of induced surge current (IEC 61000-4-5 2nd edition, tP=8/20μs) with very low clamping voltages. 


Features:

  •  ESD, IEC 61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC 61000-4-4, 40A (5/50ns)
  • Lightning, 10A (8/20 as defined in IEC 61000-4-5 2nd edition) for AQHV12
  • Low clamping voltage
  • PPAP capable
  • Low leakage current
  • AEC-Q101 qualified
  • Moisture Sensitivity Level (MSL -1)
  • Halogen free, lead free and RoHS compliant 

Applications:

  • LED Lighting Modules 
  • Portable Instrumentation 
  • General Purpose I/O 
  • RS232 / RS485 
  • CAN and LIN Bus 
  • Automotive application
