TVSs, Varistors and MOVs are used to protect sensitive electronic equipment from transient voltage disturbances. The VDRS07H420BSE is a popular Varistor and MOV device that provides reliable and effective protection for sensitive components in a wide variety of applications.

The varistor is a voltage-dependent resistor that is used for suppressing surges and spikes in voltage. Varistors are usually multi-terminal devices that are connected in series with the power supply or signal lines they are protecting. When a voltage spike or surge occurs, the varistor device provides a short-circuit path for the excessive current, essentially diverting the surge away from the protected equipment. The VDRS07H420BSE varistor is made of Metal Oxide Varistors (MOVs) which are designed for use in power applications.

MOVs are semiconductor devices that limit or suppress transient voltage surges. MOVs are typically built with a dielectric material such as zinc oxide that provides a protective layer between two metal plates. When a transient voltage spike or surge occurs, the dielectric breaks down allowing current to flow between the metal contacts. This allows the current to be drawn away from the protected electronic equipment.

The VDRS07H420BSE Varistor and MOV device is ideal for use in sensitive electronic equipment such as computers, medical devices, audio-visual equipment, and telecommunications. The device provides a maximum peak reverse voltage of 420V and a maximum working voltage of 350V. The device has a maximum leakage current of 5mA and a maximum power dissipation of 20W. The device also provides excellent circuit protection with a minimum breakdown voltage of 75V. The device has a response time of less than 500 V/us and a peak surge current rating of 40KA.

The VDRS07H420BSE Varistor and MOV device is easy to install and is designed to be mounted parallel to the circuit board. When installed, the device provides balanced protection from transient voltage surges and provides a short-circuit path for excessive current. The device can also be used in parallel with other varistors or MOVs to provide additional protection. In addition, the device has a high ambient temperature resistance and is RoHS compliant.

In summary, the VDRS07H420BSE Varistor and MOV device is a reliable and effective protection device for sensitive electronic equipment. The device has a maximum peak reverse voltage of 420V, a maximum working voltage of 350V, and a maximum leakage current of 5mA. The device also provides excellent circuit protection with a minimum breakdown voltage of 75V, a response time of less than 500 V/us, and a peak surge current rating of 40KA. The device is easy to install and provides balanced protection from transient voltage surges. The device is also RoHS compliant and has a high ambient temperature resistance.
