TVS - Varistors, MOVs are electro-mechanical devices that protect electronic circuits from overvoltage transients, such as those generated by inductive loads, lightning, or induced noise. One of the most commonly used in such applications is the VDRH10S275TSE Varistor.

A Varistor is a voltage-dependent, non-linear, symmetrically clamped, semiconductor diode. It has a wide range of application fields, ranging from consumer electronics to industry, telecommunications, automotive, and transportation information systems.

The VDRH10S275TSE Varistor is highly suited for use in transients immunity testing, EMI/RFI applications, and power supply protection due to its low resistance and fast response time. The device is designed to suppress overvoltage transients of up to 270 volts (AC) with currents of up to 55Amps over a wide range of frequencies (16kHz- 5MHz).

In operation, the Varistor acts like a voltage-dependent resistor. When the applied voltage across it is below its working voltage (V1), the Varistor exhibits an open circuit behaviour, with negligible resistance. However, when the voltage across it is higher than V1, the resistance of the Varistor decreases progressively.

This property of the Varistor allows it to rapidly ‘clamp’ the voltage applied across it to its working voltage, resulting in a decrease in the current passing through the device. This fast response time of the Varistor helps to protect sensitive electronics during voltage spikes.

The VDRH10S275TSE Varistor is housed in a compact housing, making it well suited for applications that have limited space. The device is also typically inexpensive when compared to other surge and protection devices, which further increases its appeal. In addition, its solid state design helps to ensure reliable and stable performance, even in harsh industrial environments.

In conclusion, the VDRH10S275TSE Varistor is an ideal choice for applications such as transients immunity testing, EMI/RFI applications, and power supply protection. Its fast response time and low resistance make it well suited to applications that require effective and reliable overvoltage protection.
