TVS – Varistors, MOVs

TVS (Transient Voltage Suppressor) or Varistors are non-linear devices whose main purpose is to protect circuits from voltage surges. They are mounted on Printed Circuit Boards or other electronic components. MOVs (Metal Oxide Varistors) are the most common type of Varistor, designed to provide surge and transients protection to electronic components. The VDRS10D025TSE Varistor is an efficient and reliable surge protecting device used in industrial and commercial applications.

VDRS10D025TSE Application Field and Working Principle

The VDRS10D025TSE Varistor is designed specifically for use in industrial and commercial applications for voltage surge protection. It is widely used to protect circuit boards, electronic components, and other sensitive electronic devices from transient voltages and overvoltage. The Varistor features a low impedance of 10Ω and a high energy absorption capability of 25 volts. The Varistor also features a fast response time and a high peak current carrying capacity of 5.5kAmp.

In addition to its surge-protective capabilities, the VDRS10D025TSE Varistor also serves as an AC line filter to filter out excessive high-frequency noise. The Varistor also has a high temperature coefficient, ensuring that it can withstand the high temperatures generated by the electronic components. The Varistor’s wide operating range from -40 to +125°C ensures that it is able to operate under a range of environmental conditions.

The working principle of the VDRS10D025TSE Varistor is based on the “Zener effect”. The Varistor is basically an unidirectional diode that will clamp voltages that passes above its voltage rating. When the Varistor is exposed to overvoltage, the diode conducts current, thus absorbing the excess energy. This protects the electronic components from the overvoltage.

The VDRS10D025TSE is constructed with zinc oxide as the nonlinear material, a metal oxide layer, and two electrodes. When a reverse voltage is applied to the Varistor, electrons move quickly through the metal oxide layer and form a low-resistance layer. This layer provides the Varistor with fast, efficient surge protection. When the transient voltage exceeds the Varistor’s voltage rating, the electrons are quickly pulled back and the current is dissipated.

The VDRS10D025TSE Varistor is a reliable and robust surge protector. It is designed for use in a wide range of electrical and electronic applications including power supplies, digital signals, analog signals, motor control, and more. Its combination of features, including high energy absorption capability, low impedance, fast response, and high temperature coefficient make it an ideal solution for surge protection.
