A transient voltage suppressor (TVS) is a device used to limit and suppress the amplitude of transient voltage in a circuit. Overvoltage or transient voltage spikes can be generated in a circuit, potentially causing damage to electronic components or instability in the system. To protect circuits and components, transient voltage suppressors are employed. Their operation is typically based on the electrical characteristics of components such as variable resistors, diodes, or metal oxide varistors. These components have fast response times and high voltage suppression capabilities, allowing them to quickly absorb and dissipate overvoltage, thereby keeping the circuit voltage within a safe range.
