Transients are a common problem in electronic systems due to various naturally occurring conditions like lightning strikes, electrostatic discharge, or power surges. These can cause rapid and large voltage spikes, which may damage the system components or even lead to complete system failure. A Transient Voltage Suppressor or TVS diode is a solution for these problems. It provides overvoltage protection to electronic circuits and prevents such transient voltage spikes from causing damage and malfunctioning on sensitive electronic components.
