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.
