TVS - Varistors, MOVs

Varistors, also known as Metal Oxide Varistors (MOVs), are electrical components used to protect other electrical components from spikes in voltage. The VDRH05E275BSE is a varistor designed with a high pulse-power handling capability for overvoltage protection and transient noise suppression, to protect against lightning-induced transients.In general, VDRH05E275BSE is an unidirectional protection component that provides excellent clamping performance under both AC and DC power applications. It is encapsulated using high temperature and flame retardant resin which ensures its exceptional durability and thermal cycling capabilities, ensuring it functions reliably over long periods of time. VDRH05E275BSE also features a low leakage current, high creepage distance, low capacitance, and fast response time to fast transients.The VDRH05E275BSE application field is broad and ranges from automotive, consumer electronics, DC/DC converters, and Industrial controllers to communications, computing and data processing systems. It is also used in a variety of power supplies and as an alternative to SMD Varistors.There are many applications for the VDRH05E275BSE, including protection from over voltage and overcurrent in AC/DC and DC/AC power systems, keeping circuit noise from entering the system, and clamping the output voltage from an AC source to protect it from lightning strikes. Additionally, when using the VDRH05E275BSE in a power system, it can help to reduce energy losses caused by the line inductance, helping to reduce costs.The working principle of the VDRH05E275BSE is based on the varistor effect, which occurs when voltage is applied to a nonlinear resistor/conductor. In this instance, the resistance of the VDRH05E275BSE increases with increasing voltage. When a surge of current or a short-term change in voltage is present, the resistance of the VDRH05E275BSE will then decrease. This change in resistance will limit the amount of current that can pass through the component, protecting the remaining components in the system from severe electrical damage.The VDRH05E275BSE is an incredibly useful and versatile product, with many applications and benefits. Its wide voltage and pulse power handling range, along with its durability, make it an exceptional choice for many different projects requiring high-level protection from transients. By using this product, users can be sure that their electrical systems will remain safe and unharmed from outside electrical disturbances.
