TVS is an acronym that stands for Transient Voltage Suppressor. It is a device designed to protect high voltage circuits and systems from surges in voltage and current that are caused by switching, electrical shorts, lightning, or static electricity. The B72650M0500K072 is a type of TVS varistor that is ideal for applications requiring reliable surge protection. This article will discuss the application field and working principle of the B72650M0500K072.

Application Field

The B72650M0500K072 is a high voltage TVS varistor designed to protect equipment and circuits against electrical overvoltages due to transient exposures such as lightning or power failures. It is ideal for use in circuit protection, motor control, automotive, and industrial choke coils. It is also ideal for applications requiring very small size, high reliability, and high protection up to 500A.

The B72650M0500K072 has been designed to provide effective overvoltage protection in both alternating current (AC) and direct current (DC) circuits. It can be used in a variety of commercial, industrial, automotive, motor control, and lighting applications, providing a reliable way to protect against damaging over-voltage events. The small size of the B72650M0500K072 allows it to be used in tight spaces and the low internal capacitance allows for fast response times.

Working principle

The B72650M0500K072 is a metal-oxide varistor (MOV) device that works with a principle called the zener effect. The zener effect occurs when voltage is applied to a pn junction diode. When voltage exceeds the breakdown voltage of the diode, a large reverse current will be generated. This reverse current is then used to limit the voltage across the diode.

The B72650M0500K072 operates on a similar principal. When a surge of voltage or current is applied to the device, the metal-oxide varistor is triggered and its internal resistance increases rapidly. This increases the current path for the surge and minimizes the voltage across the varistor, thus limiting the surge and protecting the circuit or system.

The B72650M0500K072 has been designed to be highly reliable and effective in suppressing transient overvoltages. It is made of highly reliable metal-oxide material and has a low internal capacitance, allowing it to respond rapidly to transient voltages. It also has a high dielectric strength, allowing it to withstand high voltages without failing. Its small size makes it ideal for use in confined spaces or applications requiring a low installation profile.

In summary, the B72650M0500K072 is a high voltage transient voltage suppressor designed to protect circuits and systems against overvoltages caused by transient exposures such as lightning or power failures. It is designed with the zener effect principle and is made of a high quality metal-oxide material. Its small size and low internal capacitance make it ideal for applications that require reliability and high protection up to 500A. It is an ideal solution for use in a wide range of commercial, industrial, automotive, motor control, and lighting applications.
