TVS - Varistors, MOVs are often used as protective devices for overvoltage applications. The VDRS07H350TSE is a product from a series of semiconductor varistor devices specifically designed for this purpose and are available in a range of standard package sizes and values. The VDRS07H350TSE varistor device is an axial-leaded, two-terminal device, designed to provide protection against transient overvoltages.

The VDRS07H350TSE varistor has an operational voltage range between 7 and 350 volts and a peak surge or transient current rating of 5 kA. The device is constructed from non-toxic, non-carcinogenic zinc oxide material, lead-free in construction, and non-polar in behavior. Its temperature rating is between -40 and +85 degrees Celsius, allowing flexible and reliable solutions in a wide range of overvoltage protection applications.

The VDRS07H350TSE can be used in a variety of applications, such as lightning protection for telecommunications equipment, line cards, power supplies, and industrial / home appliances. It is also an ideal solution for applications exposed to electrical transients, and is capable of limiting and diverting potentially damaging surges and spikes without the need for follow-up protection components. The device is intended for low-voltage and highly reliable applications such as alternative energy installations, protective relays, and more.

The working principle of the VDRS07H350TSE is based on the positive temperature coefficient of zinc oxide. This ensures that the device will “clip” the voltage waveform when the voltage exceeds the operational voltage range, limiting the magnitude of the waveform and thus, preventing damage to the underlying equipment.

The VDRS07H350TSE’s unique design also ensures low-resistance, maximum-capacity, and improved service life. During each surge, the device dissipates a certain amount of energy, which causes the device’s resistance to rise and thus, preventing future spikes from damaging the device. This also protects devices that are connected downstream of the VDRS07H350TSE.

In addition, the low-resistance element of the device enables a wider protection band and improved dielectric strength, making it suitable for applications with higher DC power. The VDRS07H350TSE can also be used in series with a fuse (which is optional), making it suited for applications where sensitive electronic components require additional protection.

Overall, the VDRS07H350TSE has a broad range of application field and excellent working principle, making it an ideal choice for overvoltage protection solutions. The device also has low capacitance, low-resistance electronics, and superior surge capability.
