TVS – Varistors, MOVs

Varistors, also known as voltage-variable resistors, and MOVs (metal oxide varistors) are two common types of supplies of Transient Voltage Suppressors (TVS) used for overvoltage protection. Varistors, MOVs, and other TVS devices work by limiting excessive voltage within a circuit. The purpose of this article is to explain the application field and working principle of V47ZU20PX10, which is a commonly used TVS device.

Application Field of V47ZU20PX10

The V47ZU20PX10 is a bi-directional, high-level transient voltage suppression diode. It is designed to protect sensitive electrical and electronic circuits against voltage transients such as electrostatic discharge (ESD), lightning, and inductive loads. It is used in a wide range of applications, such as AC/DC switch mode power supplies, motor control systems, telecommunications, automotive systems, and more.

Working Principle of V47ZU20PX10

The V47ZU20PX10 operates using the P-N junction diode principle. The P-type material enables electrons to flow in one direction, while the N-type material allows holes to flow in the opposite direction. When a voltage rises above the breakdown voltage (VBR), the junction becomes forward biased and the silicon diode breaks down. This causes a current surge that overloads the junction to quickly suppress voltage transients. Once the transient is over, the P-N junction quickly recovers and is ready for its next task.

Conclusion

The V47ZU20PX10 is a common TVS device that is used in a wide range of applications. It operates using the P-N junction diode principle, which allows it to quickly suppress voltage transients above the breakdown voltage (VBR). By understanding the application field and working principle of V47ZU20PX10, circuit designers can choose the right device for the job and ensure the safety of their design.
