Thyristors - SCRs belong to an electronic switch category, which is triggered by voltage, not current. 25TTS08STRL thyristors are a type of thyristors which are designed to satisfy the requirements of medium and high power switching applications. This article will provide an overview of their application field and working principle.

Application Field of 25TTS08STRL Thyristors

25TTS08STRL thyristors are commonly used in medium and high power switching applications, such as electric drives, motor control, power supplies, UPS, soft starters and battery chargers. These devices can handle up to 25 A of current and 800 V peak voltage. They are used to switch power electronic circuits on and off.

25TTS08STRL thyristors can also be used in electronic devices, such as electronic transformers, inverters, heating systems, LED lighting and security systems. They are also suitable for power factor correction and voltage regulation in industrial power systems. Furthermore, due to their fast switching capabilities, these devices can be utilized in the control of various types of motors, such as induction motors and brushless DC motors.

Working Principle of 25TTS08STRL Thyristors

25TTS08STRL thyristors have a four-layer structure with a gate electrode embedded in the semiconductor. When the thyristor is off, the anode-cathode junction is reverse-biased which prevents current from flowing between the two terminals. To switch on the thyristor, an external gate signal must be applied. This gate signal will trigger the thyristor, making the anode-cathode junction forward-biased, thus allowing current to flow between the two terminals.

Once the thyristor is triggered, it will remain in its conducting state regardless of the gate voltage. The only way to switch off the the thyristor is by reducing the current flow to zero. This can be done either by removing the gate signal or decreasing the supply voltage. As soon as the current flow drops to zero, the thyristor will switch off and will remain off until a new gate signal is applied.

Conclusion

25TTS08STRL thyristors are an important part of medium and high power applications. The main advantage of these devices is their fast switching capabilities, which can be utilized to control various types of electronic systems. This article has provided an overview of their application field and working principle.
