AQ3400, 1pF, 30ꢀk Diode Array
Description
The AQ3400 integrates 2 channels of low capacitance
steering diodes and an additional zener diode to provide
protection for electronic equipment that may experience
destructive electrostatic discharges (ESD). The AQ3400 can
safely absorb repetitive ESD strikes above the maximum
contact level specified in IEC 61000-4-2 international
standard (Level 4, ±±kꢀ contact discharge) without
performance degradation.
The low off-state capacitance makes it ideal for protecting
high-speed signal lines such as USB2.0 or USB 3.0 and
1Gb Ethernet with an extremely low dynamic resistance to
protect the most sensitive, state of the art chipsets against
ESD transients.
