The ESDS31x devices are unidirectional TVS ESD protection diode array for Ethernet, USB and general purpose data line surge protection up to 25A (8/20µs). The ESDS31x devices are rated to dissipate ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard (Level 4).

The devices feature a 4.5pF IO capacitance per channel making the device an excellent choice for protecting high-speed interfaces such as Ethernet 10/100/1000, USB 2.0 and GPIO. The low dynamic resistance and low clamping voltage provides system level protection against transient events.

Evaluation board

ESDEVM — ESD evaluation module

The electrostatic-sensitive device (ESD) evaluation module (EVM) is a development platform for most of our ESD portfolio. The board comes with all traditional ESD footprints in order to test any number of devices. Devices can be soldered onto their respect footprint and then tested. For typical (...)
