3 Description

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.
