The TVB270SB-L is also used in lighting and HVAC systems, where its high reliability and performance is ideal for controlling large loads.

Working principle

Thyristors are voltage-driven devices that are used to control the flow of current in an electrical circuit. Thyristors are semiconductor devices that can be used to switch current in both directions. In the OFF state (with no current flowing through the device), the Thyristor can be switched ON by passing a positive voltage across its anode and cathode terminals. Once the Thyristor is ON, it will remain ON until the current flowing through it drops to a low enough level. This process is known as “commutating” or “turning off” the Thyristor.

When the voltage is removed, the Thyristor will remain ON until the current drops to a low enough level. This process is known as “restoring” the Thyristor. As soon as the voltage is removed, the Thyristor will begin to conduct current in the opposite direction. This process is known as “reverse recovery” and it is a very important part of the Thyristor operation. Since the Thyristor is a current-controlled device, it is important to ensure that the proper current levels are applied for optimal performance.

The TVB270SB-L Thyristor is designed with advanced technology and features that provide high-performance and reliable operation. The Thyristor is designed with solid-state control and reliable switching characteristics. It is a robust device designed with low power dissipation and to operate in high-temperature environments.
