Thyristors are a type of semiconductor used for switching and controlling electrical circuits. They are also used in other applications, such as power factor correction and dynamic voltage limiting. The P2356UCRP is a thyristor-based TVS (Transient Voltage Surge Suppressor) that is designed to prevent power surges in electrical circuits caused by lightning or other high power events. In this article, we will discuss the application field and working principle of the P2356UCRP TVS.

Application Field

The P2356UCRP TVS is a bi-directional AC and DC transient voltage surge suppressor specifically designed to protect against surges due to lightning. Therefore, it is an ideal choice for high-power applications such as industrial process control, lightning protection, motor control, and power quality improvement. The device is especially suited for applications where sensitive load parts, such as power module transistors, are connected to the circuit.

The device is certified to UL1449, CSA 22.2 226, and IEC61000 standards. This means that it is suitable for all types of buildings, industrial, and outdoor environments. Additionally, the P2356UCRP has a low capacitance which means that it will not interfere with the system’s signal transmission. Furthermore, it features high surge handling and current limitation capabilities, making it suitable for protecting sensitive electronic components such as microchips and integrated circuits.

Working Principle

The P2356UCRP TVS works on the principle of crowbar protection. This type of protection works by detecting a surge in the electrical current in the circuit and then disconnecting the circuit in order to prevent any damage that could be caused by the surge. The device operates in a single direction and has two terminals for connection to the line. The device acts as a rectifier, converting the incoming surge into a current that is channeled safely away from any sensitive components in the circuit.

When the voltage reaches the TVS’s breakdown voltage, the thyristor will switch on and direct the current away from the load, thus preventing any damage that would otherwise occur. Additionally, the device features a very low thermal resistance, which means that it can quickly recognize and act on a surge, preventing it from damaging components.

The P2356UCRP TVS is a highly reliable device that can be used in a variety of applications to protect against transient voltage surges. It is simple to install and provides excellent protection with minimum interference to the system’s signals. With its low capacitance and high surge handling capabilities, it is an ideal choice for protecting sensitive electronic components and ensuring the maximum system stability.
