Design Requirements

A typical operation for the ESDS314 would be protecting a high speed dataline similar to one shown in Figure 13. In this example, the ESDS314 is protecting an Ethernet PHY's data lines that has a nominal operating voltage of 3.6 V. Many of the Ethernet interfaces that connect to long cables require protection against ±1 kV surge test through a 42-Ω coupling resistor and a 0.5 µF capacitor, equaling roughly 24 A of surge current. Without any input protection, if a surge event is caused by lightning, coupling, ringing, or any other fault condition, this input voltage will rise to hundreds of volts for multiple microseconds, harming the device.

For Ethernet 1000Base-T (1Gbps), application design parameters listed in Table 1 are known.
