For surge transients, high-energy content is characterized by long pulse duration and slow decaying pulse

power. The electrical energy of a transient that is dumped into the internal protection cells of a transceiver is

converted into thermal energy, which heats and destroys the protection cells, thus destroying the transceiver.

Figure 8-5 shows the large differences in transient energies for single ESD, EFT, surge transients, and an EFT

pulse train that is commonly applied during compliance testing.
