The performance of complementary ESD/Lightning pro- tection devices being exposed to EMP was studied. We studied pro- tection devices such as GDT (Gas Discharge Tube), TVS (Transient Voltage suppressor), and Varistor. The EMP signal has a very fast rise time of 100psec and the maximum peak voltage of 2kV. The GDT could not protect the EMP signal. The varistor showed about 35% of protection ability, and the TVS showed about 50% of protection abil- ity. Thus the GDT is not a proper device to protect EMP. However, all of the protection devices did not show their nonlinear property.
