SMP80MC-270 TVS - Thyristors - Application Field and Working PrincipleThyristors are a type of electronic component that finds widespread usage in many industrial applications. A Thyristor, also known as a Silicon Controlled Rectifier (SCR), is an electronic device that utilizes semiconductor material to allow an electrical current to flow along both directions, just like a diode. However, the thyristor has a specific characteristic that distinguishes it from other semiconductor devices, in that it can control the flow of the current flowing through it. This is achieved by manipulating the gate current and hence it is called a controlled rectifier.The SMP80MC-270 is a state-of-the art Thyristor which is one of the many variants of the Thyristor family in the market. It is a Mini-Pak package of low capacitance surge protective device consisting of a pair of Silicon Controlled Rectifier (SCR) for overvoltage protection and two soft recovery diode for transient voltage surge suppression. This design has a number of advantages for designers and users alike in controlling and regulating the surge of voltage in the system.The primary application of the SMP80MC-270 is in the area of power control. It is widely used in the safety circuits as a fuse-less short circuit protection device, as it is extremely reliable and ensures that the power supplies do not suffer due to voltage fluctuations. In addition, it also prevents any permanent damage to the circuit by cutting off the surges when a certain level is reached. The SMP80MC-270 is also used for other safety purposes such as in automobiles to prevent accidental sparking and in medical equipments to ensure that it does not go beyond the stipulated level.The SMP80MC-270 works on the principle of gate switching. It has an SCR with a gate which controls the flow of current. When a voltage in the specified range is applied, the SCR switches on allowing current to flow in one direction. When the specified voltage is removed, the SCR switches-off thereby preventing further current flow.The SMP80MC-270 also includes the soft-recovery diode which helps in preventing voltage transient surges and ups and downs, helping to maintain consistent voltage in the system. This helps to provide better protection from power fluctuations to the circuitry.In short, the SMP80MC-270 is an extremely reliable Thyristor that helps to prevent any permanent damage due to power fluctuations. Its primary application is for providing power control, prevention of short circuit damage, protection from accidental sparking and controlling surge in medical devices. It works on the principle of gate switching and also includes a soft-recovery diode for better protection from power fluctuations.
