3 Description
The ESDS302, ESDS304 devices are uni-directional
TVS ESD protection diode array in two and four
channel configurations respectively, for Ethernet and
USB surge protection up to 12A (8/20μs). The
ESDS302, ESDS304 devices are rated to dissipate
ESD strikes up to 30kV per the IEC 61000-4-2
international standard (> Level 4).
The devices features a 2.3pF IO capacitance per
channel making it an excellent choice for protecting
high-speed interfaces such as Ethernet™ 1G and USB
2.0. The low dynamic resistance and low clamping
voltage provides system level protection against
transient events.
The ESDS302, ESDS304 devices are offered in the
industry standard 5-pin SOT23 packages.
