A multi-stage surge protection device protects against complex, time-variant voltage transients, including those resulting from a high-altitude nuclear electromagnetic pulse or a solar coronal mass ejection. The transient voltage suppressor limits the let-through voltage to a clamping level and provides indication to the crowbar circuit when it is no longer able to do so.

A low-pass filter can be added to significantly lower the let-through voltage of the device for short-duration pulses, and help to spread the energy to more effectively utilize the transient voltage suppressor.
