Current will flow through the line transformer transferring energy to the PHY side of the transformer. Figure 7 shows the test set-up for measuring the clamping voltage of the device. This set up is designed to test the surge in an actual gigabit Ethernet (GbE) circuit. Two 4.7 Ohm resistors is used for decoupling. The clamping voltage of the SLVU2.8-4N for a metallic mode 4000V (100A) 10/700μs surge. The clamping voltage, measured at less than 13 volts, provides sufficient clamping margin to minimize electrical stress and is well below the failure voltage range of typical GbE PHY chips (Figure 8 ).
