The B72440P5040S260 is a varistor designed by EPCOS, a TDK Group world leading supplier of audible components and specialized in passive components located in Europe. The B72440P5040S260\'s application field covers the industrial, automation, transportation/infrastructure, automotive, residential and commercial markets. It provides optimal protection in AC- and DC power supplies to detect surges in the voltage across the two terminals of AC supply or DC lines.

A varistor is a type of voltage dependent resistor that is used to absorb energy created by voltage surges. It is also known as a voltage-dependent resistor (VDR) or a transient voltage suppressor (TVS). These devices consist of a metal oxide film, which has a low voltage breakdown characteristics and a high voltage breakdown characteristics. The metal oxide film allows for a large amount of energy to be absorbed or released in the form ofresistive heating. In the B72440P5040S260, the maximum allowable operating voltage is 500V and the limiting non-repetitive peak voltage is 2000V.

Various applications of the B72440P5040S260 includes transient voltage protection, surge protection, spike protection, high-frequency noise suppression and over-voltage protection. It can also be used as a stabiliser or energy absorber in AC/DC power supplies. The main application of the B72440P5040S260 is for unidirectional or bidirectional protection of AC/DC power supplies found in industrial, automation, transportation/infrastructure, automotive, residential and commercial markets.

The working principle of a varistor is based on the electrical property of a reversely biased field effect semiconductor. When the semiconductor is reversely biased with a voltage it creates an electric charge. The electric charge then start to flow between the two terminals of the varistor device. This electric charge then generates a sufficient amount of energy to be absorbed or released. This energy is able to absorb or release short-term transients of the voltage surge.

The B72440P5040S260 can handle multiple types of surges such as a single spike or multiple repeats of surges due to its absorption capability. It is also capable of handling high-frequency noise such as electrical noise from voltage oscillations generated in load switching, ground paths, and transmission lines. The device is designed to trigger either a latching circuit breaker or relay device when the surge voltage exceeds the maximum allowable operating voltage.

The B72440P5040S260 has been designed to provide reliable protection and performance in AC/DC power supplies. Its reliable protection and ability to absorb energy from high-frequency noise makes the device an ideal choice for surge protection. The device\'s reversely biased field effect semiconductor incorporates a metal oxide film that allows for a large amount of energy to be absorbed or released. Its overall design and flexibility make it an ideal voltage dependent resistor that can be used for numerous applications.
