TVS – Varistors, MOVs are components that are used in electrical circuits to limit the voltage of a system to a predetermined level. V120RA16 is one such component which is often used in a variety of industries and applications. In this article, we will take a look at the applications field and working principles of V120RA16.

Applications

V120RA16 is a 400 Watts unidirectional transient voltage suppressor (TVS) which is widely used in a variety of industries. It can be used as a high-reliability and low-cost solution for protection circuits such as overvoltage and transient voltage protection, which are crucial for the functional reliability of various electronic systems. It is also often used in telecom, commercial, and industrial automation, and general purpose switching and signal line applications.

Working principle

The working principle of V120RA16 is quite simple. It essentially has two metal oxide varistors (MOVs) which work as the main voltage limiter. The MOVs act like a resistor, and they self-regulate the voltage level of a circuit by diverting any excess voltage away. This excess voltage is then dissipated by the MOVs as heat thus effectively protecting the circuit from any voltage surge. The V120RA16 has a wide operating temperature range of -55 to 85°C and an operating voltage of 6.5 to 20V.

When the input voltage of a circuit goes beyond its predetermined level, the V120RA16 will immediately absorb the voltage surge and dissipate the excess current away from the circuit. This helps in protecting the components of the circuit from potential damage due to high-voltage fluctuations. The V120RA16 is also designed with reverse polarity protection, which ensures that the component is only affected if the input voltage goes below its rated voltage.

In conclusion, V120RA16 is an ideal component for a variety of applications. It is especially useful in circuits that require extra protection against voltage surges as it can effectively regulate the voltage level and dissipate any excess voltages away. This helps in reducing the risk of any damage to the components or circuit due to sudden power fluctuations.
