The ESDS314, ESDS312 devices are unidirectional TVS ESD protection diode array for Ethernet, USB and general purpose data line surge protection up to 25 A (8/20 µs) . The ESDS314, ESDS312 devices are rated to dissipate ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4).

The devices features a 4.5-pF IO capacitance per channel making it ideal for protecting high-speed interfaces such as Ethernet 10/100/1000, USB 2.0 and GPIO. The low dynamic resistance and low clamping voltage ensure system level protection against transient events.

The ESDS314, ESDS312 devices are offered in the industry standard 5-Pin SOT23 packages.
