TVS (Transient Voltage Suppressors) are specially designed electrical components to provide protection from transient voltage spikes. Generally, they allow to pass normal currents, while protection from occasional spikes greater than a predetermined value. Varistors, MOVs (Metal Oxide Varistors), are a form of TVS.

V240RA16 is a 400W rated metal oxide varistor that delivers a high surge capability and fast response time. It is typically used to protect against large and fast transient voltage spikes. This particular component is designed in a flat rectangular form with SMT (Surface Mount Technology) as the terminal type, that allows for it to be easily integrated and shoe horned into any new or existing product layout. This rectangular size also makes it quite easy to be retrofitted into existing products and/or prototyping.

The common application field of this component is in the area of high voltage protection and in motion control circuits. In particular, it is often used in power electronic applications, like: motor control systems, robots, transformers, drives, servo motors, solar panel systems, Industrial PCs, and automotive. It also is used commonly in low-voltage industrial equipment, such as in circuit breakers and other electrical current limited applications.

The working principle of V240RA16 is related to its specific properties. Generally, this item provides a line-of-sight path between the power supply and the protected circuit. When a transient voltage surge appears, the voltage across the varistor crest is brought up to a level that surpasses the clamping voltage. It then clamps the surge to an acceptable level, thus protecting the remaining circuitry. This occurs by using its high-speed, reverse energy process, also known as the ‘avalanching effect’.

The V240RA16 component is created from a proprietary semi-conducting material grain structure. Thanks to its energy does not dissipate by heat through connections as alloy-based varistors often do. The SMT terminals enhance its response to positive and negative voltages with multiple points of contact.

In conclusion, the V240RA16 is a 400W rated metal oxide varistor that provides high surge capability and fast response time. Commonly used in applications such as motor control systems, transformers, low-voltage industrial equipment, solar panel systems, and many more, it protects the protected circuit against transient voltage spikes. The working principle is based on its physical characteristics, which enable the clamping of the surge to an acceptable level using the fast, reverse energy process. Finally, the additional advantages that this component offers, such as its rectangular form with SMT terminals, make it greatly advantageous.
