A B72540T0060M062 is a metal oxide varistor (MOV) designed to help protect against damaging transients and surges. This device can detect such transients quickly, limiting the current level in the protected circuit. MOVs offer the versatility to respond to transient events of all levels of amplitude and duration, providing protection even against lightning-induced surges.

MOVs are usually constructed from zinc oxide grains embedded in an epoxy mounted between two metal plates - allows them to be inserted into electrical circuits and effectively protect equipment and components against over-voltage and other electrical events.

A B72540T0060M062 application field is in portable electrical and electronic equipment, household appliances, telecom and datacom equipment, measurement and test equipment, AC switching applications, audio/video systems, PCs, and motor control applications. It offers an excellent suppression capability from transients, electromagnetic interference (EMI) and electrical fast transients (EFT).

The B72540T0060M062 is also ideal for consumer appliances which are already experiencing low leakage current. Its 500 VAC working voltage rating and an energy capacity of 46J make it a preferred over-voltage protection component in applications ranging from office automation to power systems and industrial environments. It can be used in both AC and DC circuits and is designed to provide high surge protection solutions in applications where an integrated MOV is preferred, like electric vehicles for instance.

The working principle of B72540T0060M062 is based on the simplified physical phenomenon of avalanche breakdown. When a voltage limit is exceeded, the zinc oxide particles in the film will be collectively broken down to form a conducting path from one electrode to another. This causes a significant current to flow, limiting the peak voltage at the junction and protecting the circuit from damage.

The response time of a surge protection device such as the B72540T0060M062 is also very short, usually less than a few nanoseconds, meaning that the protected circuit is protected from even the shortest transients. This device features a high temperature and humidity resistance, making it a reliable and robust surge protection solution, necessary for most electrical and electronic circuits.
