TVS - Surge Protection Devices (SPDs)TVS surge protection devices (SPDs) are electronic components that are used to protect circuits from transient voltage spikes, such as those caused by lightning strikes or power surges. A TVS SPD is a type of transient voltage suppression (TVS) device that is specifically designed for use in surge protection applications. It is typically a small, low-power component that is placed in parallel with the circuit that needs to be protected. When a transient voltage spike occurs, the TVS SPD will clamp the voltage to a safe level, preventing it from damaging the circuit. TVS SPDs are commonly used in a variety of applications, including power supplies, automotive systems, and telecommunications equipment.
