Regulators and components are the cornerstone of the electronics industry, allowing effective control of voltage and current in electronic circuits. Varistors (also known as voltage-dependent resistors, Varistor- Regulators, Voltage Dividers etc) are one type of regulator which acts a protective element to limit excessive voltage/current. This article will focus on the application field and working principle of a popular Varistor product: the VDR07H275TLE.

The VDR07H275TLE is part of a larger family of varistors which are typically designed for over-voltage protection in a variety of applications. These applications include power supplies, TVs and other consumer electronics, batteries, electric motors, solar panel systems and even medical devices. This type of varistor is most commonly used in consumer electronics since its easy integration, stability, competitive pricing and long life.

The VDR07H275TLEvaristor features several characteristics which make it ideal for protecting devices from over-voltages. It has an operating voltage of 275 volts, meaning it can act as a effective clamping component in devices with a higher operating voltage. Additionally, its low-clamping ratio, low series resistance and high power rating (2W) make it suitable for highly efficient over-voltage protection. Furthermore, its capacitance characteristics enable superior transient operation and response.

Despite its high efficiency, the VDR07H275TLEvaristor is simple in its principle of operation. By connecting the varistor to a power source, it acts as an open-circuit until it is exposed to a voltage greater than its rated voltage. When the current exceeds the rated voltage, the varistor begins to reduce the current flowing through the device. This is done by creating a parallel path that dissipates the excessive energy into the air, protecting the connected circuit from destruction. This process continues until the voltage is decreased and then the varistor reverts to its original state.

In addition to providing effective over-voltage protection, the VDR07H275TLEvaristor also features a wide temperature range (-55°C to +125°C). This means that it can be used in a wide range of environments and is suitable for applications in which the temperature can fluctuate. Furthermore, the device is RoHS compliant, making it a viable solution for electronic applications which have to adhere to environmental regulations.

In summary, the VDR07H275TLEvaristor is an ideal choice for over-voltage protection in a variety of different applications. It is small in size, competitively priced and has a wide temperature range, making it suitable for use in both consumer electronics and industrial applications. Furthermore, its low-clamping ratio, low series resistance, high power rating and superior transient operation make it a highly efficient protection device, offering maximum protection with minimum disruption.
