TVS - Varistors, MOVs Varistors (also known as voltage-dependent resistors) are the most commonly used form of transient voltage suppression (TVS) devices, and the ROV20H220M-2 is one such example. Varistors are designed to protect against transient voltage surges, which are large voltage peaks produced by electrical activity such as strike, lightning, and switching of inductive loads. MOVs (metal oxide varistors) are widely used for their excellent surge energy absorption capabilities and cost effectiveness.The ROV20H220M-2 is a varistor designed to protect against overvoltage conditions such as transients, spikes, and surges. It is constructed of a multilevel metal-oxide-semiconductor structure, and it features high current capability and low capacitance. The device is capable of withstanding repeated overvoltage stress and has excellent clamping capabilities. The ROV20H220M-2 is also designed with a large surge handling capacity of 250W (10/1000 microsecond).The working principle of the ROV20H220M-2 is relatively straightforward. When a transient voltage pulse is applied to the varistor, it limits the voltage across it by conducting a surge of energy. During normal operating conditions, the device acts as an open circuit, and the applied voltage is limited. When the voltage reaches its maximum threshold, the varistor starts to conduct a surge of energy, reducing the voltage across the device and protecting the circuit from overvoltage conditions. The ROV20H220M-2 is typically used in applications where surge protection is critical, such as in the automotive and industrial sectors. In the automotive industry, the device is used to protect critical components from electrical transients caused by engine ignition and switching. In industrial applications, the device is used to provide suppression for electrical equipment. The ROV20H220M-2 is also used in consumer electronic products, such as data storage devices, to provide protection against power surges and spikes.The ROV20H220M-2 is a durable and reliable device, capable of withstanding overvoltage conditions and protecting critical components in a variety of applications. The device is constructed with a multilayer metal-oxide-semiconductor structure and is designed to provide reliable surge protection for high peak current applications. The device is also designed to provide excellent clamping capabilities and is capable of withstanding repeated overvoltage stress. The ROV20H220M-2 is a cost-effective solution for electrical surge protection, making it a popular choice for electrical engineers looking for reliable overvoltage protection.
