TVS – Varistors, MOVs are common terms that apply to a host of over-voltage protection devices. A typical example is the TMOV25SP200M. It is designed to provide fast, reliable, and efficient over-voltage protection.

The TMOV25SP200M is a Metal Oxide Varistor (MOV). varistors are basically employed to protect sensitive components or the entire system against stray voltages, transients, voltage spikes, or surges and to maintain the system operating voltage within the configured ranges. It helps to improve the operational performance and life of the circuits.

The ‘SP’ in the ‘TMOV25SP200M’ refers to the device’s specific surge-protecting qualities. This product series is optimized for short-duration voltage spikes, compared to MOVs for longer duration surges which can be in the form of AC generator spikes. The ‘200M’ refers to the MOV component’s rated energy and is typically expressed in joules. It defines the amount of energy the MOV is capable of dissipating without failure or damage.

The TMOV25SP200Mis typically applied in motor control centers, residential and industrial power systems, IT systems, data centers, and electric vehicles. It is typically installed in-line between the power source and the system to provide protection.

The TMOV25SP200M works by clamping, diverting or shunt away voltage spikes. This is achieved by using the metal oxide and silicon layers within the MOV. Upon detecting an abnormal or unbalanced surge, the MOV begins to conduct the excessive current away from the circuit and absorbs the energy.

The thermal stress created between active and passive layers on the MOV is absorbed, converting it to heat, causing it to expand and filling any gaps. It works like a fuse, but does not need to be replaced like a fuse. It is not triggered until an abnormal surge of electricity is detected.

The TMOV25SP200M also supports the safeguard of electronic systems during critical moments. Its responsiveness time is fast, which helps to prevent any accidental damages due to voltage fluctuations. Its silver-based plating helps to thwart corrosion.

In conclusion, the TMOV25SP200M is an inexpensive tool for protecting electrical systems while at the same time providing improved operational performance. It is developed from the Metal Oxide Varistor (MOV) technology and is designed for short-duration voltage spikes. It is typically used in motor control centers, residential and industrial power systems, IT systems, data centers, and electric vehicles.
