10/100/1000以太网ESD保护

设计说明：

保护应用：

The data signals used in an Ethernet port vary between 1.0V and 2.5V, with maximum data rates of 1000Mbps (or 1Gb). At this speed, the capacitance of the suppressor needs to be taken into account. The signal lines to be protected from ESD and lightning transients include Tx+/- and Rx+/-.

解决方案说明：

As shown at the left, a low-capacitance TVS Diode Array (SP3002) is being used to provide up to 12kV ESD protection.

配套解决方案：

If higher levels of ESD protection are needed, the SP3050 (20kV) can be used. If smaller form factors are required the SP3004 is a good option providing the same level of ESD protection in a SOT563 package.

监管问题：

The IEC 61000-4-2 will be the most appropriate standard for ESD testing to verify that the Ethernet port is not susceptible to ESD events.
