TVS (transient voltage suppressors) are a type of electrical protection device used to protect sensitive components from electrical surges or over-voltage events. Varistors and MOVs (metal oxide varistors) are two types of TVS. Varistors are structured from semiconductor materials with a symmetric construction and have a bidirectional voltage protection capability. MOVs are made from oxides of metal semiconductors, such as zinc oxide or aluminum oxide, and have a unidirectional voltage protection capability. The VP4032K251R035 is a type of MOV.

The VP4032K251R035 is a 12-20V, 25V rated, 1.35kA peak current handling, 5-pin terminal metal-oxide varistor (MOV). It is commonly used in overvoltage protection applications such as DC/AC power supply and other associated equipment. The VP4032K251R035 has a wide operating temperature range of -40 to +105 °C, and a wide capacitance range of 0.3-2500pF.

The VP4032K251R035 is a three-terminal device that protects electrical components and circuits from transients such as electrical spikes or surges. The varistor is installed across the power lines and changes state when an inrush of current passes through it. When the current exceeds its surge current rating, the MOV changes state and begins to clamp the voltage, reducing the potential for damage to sensitive components downstream.

The working principle of the VP4032K251R035 is based on the change in resistance and capacitance of the MOV when there is an increase in voltage. When the voltage across the MOV exceeds the breakover voltage, the MOV will enter a conduction state, thereby diverting current away from the protected component. When the voltage is reduced back to its normal operating levels, the MOV will once again enter a high resistance state, thereby disconnecting power to the protected component, thus ensuring that the component remains safe.

In addition to its surge current rating of 1.35kA, the VP4032K251R035 is also rated for a maximum peak-pulse power dissipation of 470W. It also has a maximum working voltage of 25V and a clamping voltage of 40.2V.

The VP4032K251R035 is an ideal choice for applications such as DC/AC power supplies, electrostatic discharge protection circuits, industrial automation, LED lighting, medical equipment, and other industries where protection from inrush currents or over-voltage is required. Its wide capacitance range and temperature range allows it to be used in a wide range of applications.
