TVS - Varistors, MOVs, or Transient Voltage Suppressors (TVSs) are widely used in circuit protection applications. B72724A8151V062 is one such device, offering superior protection for power supplies and other vulnerable circuits. This article will detail the application field and working principle of the B72724A8151V062.

Application Field

The B72724A8151V062 is a Varistor film that is designed for use in applications that require IEC 61000-4-2 and/or ESD protection. It helps protect circuits from the high voltage surges that can occur from electric fields or other sources. It is suitable for use in a wide range of applications, including automotive, lighting,industrial, and power electronics.

Additionally, as it is a Varistor, the B72724A8151V062 provides protection for high current switching transients, and is designed to protect circuits from overvoltage transients. The B72724A8151V062 also offers excellent surge performance and a low capacitance. This makes it ideal for use in touch panel applications, as well as portable devices and electronic circuits.

Working Principle

The B72724A8151V062 is a Varistor that works on the principle of voltage dependent capacitance. A Varistor is a type of capacitor with variable capacitance; that is, as the voltage applied to the capacitor increases, the capacitance increases. This is a result of the arrangement of two plates in the Varistor, which are separated by a dielectric material. When a voltage is applied to the Varistor, an electric field is generated, which causes the positive and negative charge carriers to disperse and the capacitance of the Varistor to increase.

This increase in capacitance causes the Varistor to act as a surge absorber when an overvoltage transient enters the circuit. When the transient occurs, the increased capacitance of the Varistor acts as a resistor, absorbing the energy of the surge and reducing its magnitude.

The B72724A8151V062 is also self-limiting; that is, if the voltage applied to the Varistor increases beyond the maximum breakdown voltage, the capacitance of the Varistor will decrease, limiting the amount of energy that can be absorbed by the Varistor and preventing further damage to the circuit.

Conclusion

The B72724A8151V062 is a Varistor designed for ESD and IEC 61000-4-2 applications. It provides superior protection for sensitive circuits, and its self-limiting capabilities ensure the circuit is not damaged by excessive surge currents. The B72724A8151V062 can be used in a wide range of applications, including automotive, lighting, industrial, and power electronics, and can be used for touch panel applications as well as for portable devices.
