8.2.1 Design Requirements

An application for the TVS5800 is protecting a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller. In this example, the TVS5800 is protecting a PoE PSE controller such as the TPS23882, that has a nominal voltage of 58V and a clamping voltage requirement below 95V which is easily doable for the TVS5800 with a max clamping voltage of 75V. Most industrial interfaces such as this require protection against ±1kV surge test through a 42Ω coupling resistor and a 0.5µF capacitor, equaling roughly 24A of surge current. Without any input protection, if a surge event is caused by lightning, coupling, ringing, or any other fault condition thissd input voltage rises to hundreds of volts for multiple microseconds, violating the absolute maximum input voltage and harming the device. A desired surge protection diode maximizes the useable voltage range while still clamping at a safe level for the system, TI's Flat-Clamp technology provides the best protection design. For more information on PoE PSE controller protection, see Section 10.2 of the TPS23882 data sheet.
