TVS - Varistors, MOVs

The V47ZU1P is a components in the class of transient voltage surge suppressors (TVS). TVS components are used to protect circuits from damaging transient voltages, like lightning strikes, together with varistors and Metal Oxide Varistors (MOVs). This document provides an overview of the V47ZU1P application field and its working principle.

Application Field of the V47ZU1P

The V47ZU1P can be used in a variety of applications. It is part of the SMT-ESD Protection product family designed to protect sensitive electronics from Electrostatic Discharge (ESD). This family of products includes varistors, TVS diode arrays, capacitor arrays, and other components. The V47ZU1P TVS diode array is ideal for ESD protection of high-voltage applications such as power converters, LED lighting, and automotive electronics. It can also be used to provide protection to consumer electronics, including computers, phones, and other portable devices.

Working Principle of the V47ZU1P

The basic working principle of a TVS diode array is the same as that of any other diode: it acts as a one-way valve for electric current. In the case of the V47ZU1P, current is limited by a breakdown voltage which is lower than the maximum operating voltage of the device. When a transient voltage exceeds the breakdown voltage of the diode, current is quickly and safely discharged. This prevents the damaging spikes from reaching the circuit.

The V47ZU1P is designed with special construction that ensures optimal protection without sacrificing the performance of the system. The diode array features low clamping voltage, fast response time, and low leakage current. The diode is equipped with a three-stage voltage regulator that prevents overshoot when excessive transients occur. Additionally, the diode is designed with a low temperature coefficient that ensures reliable operation at extreme temperatures.

TVS diode arrays like the V47ZU1P provide superior protection against transients than do varistors and MOVs. Varistors are designed to provide protection over a narrow range of voltages, while MOVs are designed to provide protection over a broad range. The V47ZU1P, however, is designed to provide the best of both worlds by offering a wide range of protection and a fast response time.

Conclusion

The V47ZU1P is part of a class of transient voltage surge suppressors (TVS) that offer high levels of protection from damaging transient voltages, like lightning strikes. The diode array features a three-stage voltage regulator, low clamping voltage, fast response time, and a low temperature coefficient. It is ideal for applications such as power converters, LED lighting, and automotive electronics, where ultimate protection is needed without sacrificing performance.
