Power over Ethernet (POE) interface power supply protection circuit diagram capable of maintaining signal integrity on the interface

The TVS array operates at 5V with low line-to-line capacitance to maintain signal integrity on high-speed interfaces. When the PoE signal pair is at different DC potentials, the innovative split-pad TVS architecture achieves the critical electrical isolation required between PoE differential pairs while maintaining robust surge immunity in a single pair. The RClamp0524S is available in a SOT-236L package with an integrated diode array for efficient layout and is ideal for PCB layout and parasitic applications including wireless access points, VoIP phones and digital surveillance cameras. The RClamp0524S can be mounted on a PCB board or inside an RJ-45 connector with limited board space.
