The VDRH2O X625BSE is a general-purpose overvoltage protection device. It is a non-linear component which is used to protect sensitive electronic circuits from over-voltage conditions. The VDRH2O X625BSE is a one-stage device which is comprised of two metal oxide varistors (MOVs) with a series combination connection.

The two MOVs are connected in series for enhancing the overall protection parameters of the device. The two MOVs share a common impedance, which is provided by the VDRH2O X625BSE configuration. The VDRH2O X625BSE is a two-stage device which provides a higher level of protection than single-stage devices. The VDRH2O X625BSE offers a lower peak current, a lower peak voltage, and better noise suppression, compared to other single-stage MOVs.

The VDRH2O X625BSE is typically used in applications such as computers, consumer electronics, storage devices, medical devices, wireless communication systems, and automotive electronics. It can also be used in other applications such as power supplies, solar applications, industrial equipment, and home appliances.

The working principle of the VDRH2O X625BSE is based on thermally and galvanically activated varistors. When an overvoltage occurs, the voltage across the MOVs rises, creating an electrical field between the two MOVs. This field causes a current to surge through the device, which dissipates the excess energy. The current dissipated in the MOVs is proportional to the varistor voltage, which is determined by the capacitance of the device.

This surge current dissipates heat which causes the temperature of the MOVs to rise. When the temperature of the MOVs reaches a certain threshold, a second stage of protection is activated, allowing the surge current to be diverted to the ground. This protects the circuits from further harm.

The VDRH2O X625BSE is an effective protection device, which provides superior protection from overvoltage. It is suited for a wide range of applications, and can be used in both single-stage and two-stage protection systems. Its superior performance and reliability make it an ideal choice for applications with sensitive and high power components.
