The device diagram on this page shows a closer view of the PoE TVS solution discussed in the previous example. This device, RClamp0524S, can be used to provide differential mode transient protection on the line side of the Ethernet interface. As any additional inductance can add to the ESD clamping of the TVS diodes, it is beneficial to place the TVS as closely as possible to the connector. The TVS array in this example offers a low line-to-line capacitance, while the dual TVS array provides the necessary line isolation as the diode pairs are separated within the package to isolate the 48V between the differential pair.
