TVS- Varistors, MOVs are important components which are utilized across a range of industries and applications. The V420LXR1192 is a combination of the two hardware components. This component has a wide range of application fields and uses, along with an associated working principle.

What is a V420LXR1192 Varistor?

V420LXR1192 is a combo of varistor and MOVs. Varistors are voltage-dependent resistor devices. They are capable of reducing the level of unwanted transients, such as surge, lightning, and high level ESD. MOVs, also known as metal-oxide varistors, are similar devices. They are used to protect the electrical system from voltage overstress and electrical transients.

Applications of V420LXR1192 Varistor

The V420LXR1192 is a high-performing, versatile component with a wide range of applications, including:

• Automotive systems – to protect vehicle electronic systems from voltage overstresses
• General purpose circuits – to protect sensitive components from voltage overstresses per IEC standards
• Computer, communication systems – to absorb ESD, EFT, or lightning spikes
• medical and military systems – to provide protection from voltage overstresses in critical applications
• Patients or people in extremely low power levels – to prevent shocks caused by the electric field
• High current applications – to effectively protect equipment from short-circuits
• Industrial, street lighting systems – to protect low-voltage power circuits

Working Principle of V420LXR1192 Varistor

The V420LXR1192 is a two-element device which operates using principles of both varistors and MOVs. When the device is not subject to voltage overstresses, it behaves like an ordinary resistor, providing a low-level resistance.

When a voltage transient occurs, the V420LXR1192 will absorb and clamp the transient, reducing the voltage and dissipating the excessive energy. This is achieved by the varistor section, which provides a high-leakage impedance and instantaneously dissipates the current. The MOV section provides a slower but more effective response to transients, providing protection against severe overstresses.
