TVS - Varistors, MOVs are devices designed to protect electrical circuits from excessive voltage. TVS devices are also known as transient voltage suppression devices or transient voltage arrestors. They are designed to limit peak voltages on circuits and protect the circuits from damage. The VDRH20X420BKE is a TVS device specifically designed for use in audio and video equipment.

Application Field

The VDRH20X420BKE is designed to be used in audio and video equipment. It is capable of providing transient voltage protection in both analog and digital applications. It can be used in a wide variety of electronic equipment, such as televisions, computers, home theater systems, amplifier boards, AV receivers, pre-amplifiers, and more. It can even be used in automotive applications.

Working Principle

The VDRH20X420BKE works by limiting the peak voltage on a circuit to a safe level. The device has a Zener diode at its core, which works to limit the voltage on a circuit. When a voltage spike occurs, the Zener diode will conduct the majority of the current, thus limiting the peak voltage. This prevents the circuit from being damaged by excessive voltages.

The VDRH20X420BKE also has a shunting capacitor, which helps protect against high frequency transients. Where a normal diode would be ineffective, the shunting capacitor helps dissipate the excess transient energy. It also works to reduce noise generated by the device, allowing for cleaner audio and video signals.

The VDRH20X420BKE can be used in a wide variety of applications to protect circuits from excessive voltage. Whether it is used in audio or video equipment, the device can be used to provide reliable protection from high voltage transients.
