TVS – Thyristors
SMTPA68 is a thyristor with a higher voltage range, with its graphite texture, and a new performance design of thick film hybrid integrated packaging technology. It is the most advanced electronic switch in the electrical rack. The use of its self-locking phenomenon helps to reduce the time used and the power consumed when switching. It is also used to increase the application reliability of the circuit. This application field and working principle of the SMTPA68 will be discussed in the sections below.
Application Field
The SMTPA68 thyristor can be used in a variety of applications, such as motor control, inverters, diverse power supplies, DC/AC choppers, controllable AC modules, and others. It can also be used in many fields such as automation, electrical equipment, medical devices, aerospace industry, railway industry, and telecom industry.
Performance Characteristics
The SMTPA68 thyristor has several excellent performance characteristics which make it ideal for use as an electronic switch. Firstly, it is made of graphite structure which is highly thermally stable. The material also has excellent current handling ability and low saturation voltage. These characteristics make it more reliable for long-lasting operation in certain applications. Additionally, the SMTPA68 has a relatively low on-state voltage drop, which helps to reduce power losses when the thyristor is conducting current.
The product has good dynamic characteristics when compared to other similar designs. Its reaction time and inductive voltage are both low, allowing the necessary control and switching to take place quickly and accurately. Further, the SMTPA68’s failure mode is closed loop, which makes it more reliable in certain applications. It also has a low thermal resistance coefficient, which can help to prolong its life. Finally, the product has a relatively low leakage current, helping to reduce the amount of electricity wasted over time.
Working Principle
The SMTPA68 works on the principle of bidirectional conduction. This principle means that the conduction characteristics of the thyristor can be controlled by switching the polarity of the gate current. The thyristor is designed with a base of vertical PN+ devices, which enable it to switch when the gate current is applied in one direction and then remain off when the gate current is reversed. This type of switching is particularly useful in AC circuits because it allows for better control of the power switching and current handling.
When the gate current is applied, the thyristor begins to conduct current until the applied voltage exceeds the undervoltage threshold or the overvoltage trip angularity, at which point it will stop conducting. The thyristor will also stop conducting immediately if the gate current is suddenly reversed. This makes it possible to control the conduction of current in a much more precise manner than with other types of thyristors.
Conclusion
In conclusion, the SMTPA68 is a highly advanced electronic switch which has excellent performance characteristics and a proven working principle. Its use of graphite structure ensures excellent thermal stability and high current handling abilities. Further, its closed loop failure mode helps to minimize the risk of malfunction, which increases its reliability. Finally, the product has a low leakage current which ensures less power is wasted over time. This makes the SMTPA68 ideal for use in a variety of applications, from motor control to DC/AC choppers and automation.
