Series
General Purpose ESD Protection - AQxx
SD Series
AQxx Series 450W Discrete Unidirectional TVS Diode
RoHS
Pb GREEN
Description
The unidirectional AQxx 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 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.
