Introduction

A TVS - Mixed Technology is an important tool for application protection and prevention of transient voltage transient. As its name implies, a TVS - Mixed Technology combines both Transient Voltage Suppressor (TVS) and Varistor (Var) design elements into one system. The ESDU02A3V3R17V is a high-performance device for use in industrial and consumer applications which combines both TVS and Varistor designs to provide an excellent 5.0kV of breakdown voltage and low leakage. In this article, we will discuss the working principle and application field of the ESDU02A3V3R17V.

Working Principle

The ESDU02A3V3R17V combines both the TVS and Varistor working principles in order to provide excellent surge protection. The TVS portion of the device works by diverting a surge of energy away from sensitive components. The Var portion of the device, when combined with the TVS, creates an ideal mixture of robust protection and low leakage current. The key aspect of the TVS working principle is the low capacitance, allowing the device to respond quickly to surges, while still providing a low on-state resistance for low-level protection. This low capacitance is the result of the device\'s series device architecture. The device also features a low-voltage turn-on performance, making it ideal for protecting low-voltage systems. The Var portion of the device works by providing a radially symmetric field around the device which clamps the voltage between its breakdown and clamping values. By providing both the TVS and Var functions in one device, the ESDU02A3V3R17V offers both robust protection and low leakage current in a single solution.

Application Field

The ESDU02A3V3R17V is an ideal solution for providing both robust protection and low leakage current in applications such as consumer electronics, industrial equipment, power supplies, and general purpose applications. The device\'s 5.0kV immunity ratings make it suitable for a wide range of applications. It can be used for overvoltage protection for direct current, or reverse current protection for switching power supplies. The ESDU02A3V3R17V can also be used for isolation and signal isolation in automotive, medical, and telecom applications. Its low capacitance and low-impedance design also make it suitable for transceivers, receivers, and other high-speed applications. The device\'s small size and high power rating make it perfect for space-constrained applications such as PCBs.

Conclusion

The ESDU02A3V3R17V is a high-performance device which combines both TVS and Varistor design elements for excellent surge protection and low leakage current. The device is suitable for a wide range of applications due to its immunity ratings and its low capacitance and low-impedance design. The device\'s small size and high power rating make it an ideal solution for space-constrained applications.
