The AQHVxx-01ETG-C series is designed to provide an option for very fast acting, high performance over-voltage protection devices. 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. The AQHVxx-01ETG-C series 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 8A (AQHV12-C) of induced surge current (IEC 61000-4-5 2nd edition, tP=8/20μs) with very low clamping voltages.
