Normal input

At the working voltage the TVS is reverse biased; leakage remains.

Transient arrives

As the junction enters breakdown, reverse current rises and limits the rail excursion.

Energy and fault protection

The surge must stay within the pulse envelope. A coordinated fuse or other upstream protection handles sustained faults.
