TVS Diode Arrays (SPA® Diodes)
Enhanced ESD Discrete TVS Series - AQ3522-01FTG
SP3530
AQ3522-01FTG, 0.15pF 22kV Bidirectional TVS diode
RoHS Pb GREEN
Description
The AQ3522-01FTG integrates ultra low capacitance diodes
to provide protection for electronic equipment that may
experience destructive electrostatic discharges (ESD). This
robust component can safely absorb repetitive ESD strikes
above the maximum level specified in the IEC 61000-4-2
international standard (Level 4, ±8kV contact discharge)
without performance degradation. The extremely low
loading capacitance also makes it ideal for protecting high
speed signal pins such as V-By-One®, HDMI, USB3.0 and
USB2.0.
