Varistors, also referred to as voltage-dependent resistors, are semiconductor components with a specified working voltage, which become conductive when this material is exceeded in the circuit. TVS - Transient Voltage Suppressor, is an electrical device applied to protect a circuit from voltage transients caused by electrostatic discharge, power cross and other unusual voltage spikes. The VDR S14G025TSE is one of the most popular Varistors - MOV’s on the market today.

The S14G025TSE Varistor is a 5mm disk-type varistor device, designed to provide over-voltage protection needs such as lightning protection, surge and surge clamping. It has a rated voltage of 270VAC and a working voltage of 210VAC. The maximum clamping voltage is 1629V (10/1000μs). This device is manufactured in a fully automated manufacturing process in a ISO-9001-2015 certified plant, which ensures high quality and reliability. The S14G025TSE is RoHS & REACH compliant.

The main application area of the S14G025TSE Varistor would be the protection of equipment with a power output stage. It can be used, for example, in solid state relays and LED drivers, as well as in power amplifiers and motor controls. It is also suitable for AC/DC power supply applications, including switching power supplies in home electronics and consumer applications. The S14G025TSE Varistor can also be used in lighting fixtures, inverters, PLCs and power conditioning systems.

The working principle of the S14G025TSE Varistor is based on the concept of variable impedance. Basically, the device is a specialized semiconductor component with a voltage-dependent resistance. When the voltage across the device rises above the manufacturer-specified working voltage, the resistance of the varistor drops sharply. This sudden drop in resistance causes the device to absorb surge voltages, thus protecting the connected circuit from high surge voltages.

Overall, the S14G025TSE Varistor is a reliable and cost-effective solution for protecting electronic equipment from voltage transients, ensuring a safe and reliable operation. With its five millimetre disk-type design and high clamping voltage, it is a perfect choice for a wide variety of applications.
