B72520E0140K062

TVS - Varistors, MOVs

The B72520E0140K062 is a unidirectional transient voltage suppressor (TVS) that provides protection from damaging transient voltages in a wide range of applications, particularly those that require an exceptionally high level of protection. It is a type of varistor, and like other Varistors, its working principle is based on the property of nonlinear resistance. This principle works on the concept of a positive temperature coefficient, where the resistance of the material increases with increase in temperature.

Application Field:

The most commonly used application for B72520E0140K062 Varistors is for protecting sensitive circuitry in the industrial, automotive and consumer electron industries. It can be used to protect offf-line and AC/DC supplies, as well as be used in data communications. With its high breakdown voltage, it can also be used to reduce EMI/RFI noise for commercial and home appliances.

Working Principle:

The B72520E0140K062 Varistor is a nonlinear resistor, which means that the resistance of the material changes with voltage applied across it. This material is constructed from a combination of sintered and annealed metal oxide material which has been compressed into a cylindrical shape or disc. This combination results in a material that changes resistance relatively quickly in response to rapidly changing voltage.

The principle of operation is based on the fact that the resistivity of the material increases with increase in temperature and with increase in the applied voltage. This allows the material to act as a voltage-dependent resistor, acting as a low resistance when a small/low voltage is applied and a high resistance when a large/high voltage is applied. As a result, the material is able to clamp the voltage at a certain level, thus protecting sensitive circuitry.

Conclusion:

The B72520E0140K062 Varistor is a high-performance device that is widely used in a wide range of applications due to its exceptional voltage protection capabilities. With its nonlinear resistance properties, it is able to provide reliable protection in virtually any application without compromising on its performance.
