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.
