How it works

3 stages · Explore one step at a time

Step 1 / 3

Normal input

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

Step 2 / 3

Transient arrives

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

Step 3 / 3

Energy and fault protection

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