How to Choose the Surge Suppressor's TVS Diode

When choosing the right surge suppressor transient adapters voltage surge diodes for an outlet, various aspects should be considered to ensure excellent suppression surge while protecting system performance. Below are some considerations that will help when making the decision.

Clamping Voltage

Take careful consideration of the clamping voltage level since this is the predetermined voltage at which the diode will start conducting and clamping excess surge energy. The TVS diode's clamping voltage must be higher than the normal operating voltage of the equipment. Still, it should lower enough to prevent damage in case of voltage surges. Prolonged exposure to voltages above the breakdown voltage can damage electronics.

Peak Pulse Power

This power indicates the diode's ability to tolerate surge energy without being destroyed. The larger the pulse power, the larger the diode can handle surge energies. It only means selecting the right diode with sufficient peak pulse power for the intended application to exhaustion. Overextending the diodes' ratings may lead to failure in suppression, thereby risking equipment damage.

Reverse Standoff Voltage

This is the maximum voltage that can be applied across the diodes under normal conditions. Choose a TVS diode with a reverse standoff voltage that meets or exceeds the system operating voltage. This ensures that as long as the system operates below this voltage, the diode will not conduct and protects the outlet from transient surges. Selecting a diode with a suitable reverse standoff voltage will avoid unnecessary device operation and possible failure from overload.

Thermal Resistance

Often, this parameter is the diode's ability to withstand excessive power dissipation without affecting its performances. It's significant in applications where power surges are frequent or sustained, as high thermal resistance diodes can operate continuously without degradation. That makes it necessary to select diodes with low thermal resistance in high-power applications to ensure good voltage regulation and appliance safety.

Junction Capacitance
