TVS Diode Arrays (SPA® Diodes)
General Purpose ESD Protection - AQHVxx-01LTG Series
AQHVxx-01LTG Series 250W Discrete Unidirectional TVS Diode
RoHS Pb GREEN
Description
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.
