Signal SPD

Devices in signal systems typically contain a large number of microelectronic components, such as integrated circuits, chips, and transistors. These components have relatively low voltage withstand capacity and are highly sensitive to even minor voltage changes. Even a brief overvoltage surge may damage the components, causing equipment to malfunction or even fail completely. Surge protective devices (SPDs) can act quickly when a surge occurs, clamping the surge voltage to a safe range and diverting the surge energy, thereby protecting these sensitive devices.
