TVS - Thyristors

TVS, an abbreviation of Transient Voltage Suppression, with Thyristors, are electronic crowbar devices designed to protect circuits from high voltage surges. The TVS thyristors operate at rising overvoltage up to break-over voltage limits. These solid-state components are made from the layers of four alternate p- and n-type materials. In addition, with high-speed response and robust surge capacity, they are perfect for surge protection of communication devices, as these devices are quite sensitive.

What are the Essential Functions of TVS Thyristors?

These devices perform the following basic functions. 

• Protection - they protect individuals from harmful or unnecessary voltage triggered by lightning or power line contact. 
• High power diversion - They earth extreme transient currents, thus protecting the equipment. 
• Voltage regulations - limiting the equipment’s overvoltage to normal. 

What are the Benefits of TVS Thyristors?

These devices feature various benefits, such as:

• They are small-sized chips and are lightweight.
• They are reliable.
• They are constructed from dependable materials.
• They offer robust, high-current performance with long life.
• They are cost-effective.

Where can TVS Thyristors be Used?

TVS-thyristors suit surge protection due to their unmatchable surge capabilities. These devices are also suitable for minimizing transmission losses in a high-speed wideband transmission system. In addition, they are not favored for certain specific applications, such as protecting DC power or low impedance voltage sources.
