TVS – Varistors, MOVsVaristors and MOVs are two important technologies that are used in surge protection applications, protecting electrical systems from overvoltage surges. B72220T2251K105 is one of the most advanced varistors and MOVs available on the market. It is designed to offer superior performance over other existing surge protection technologies.The B72220T2251K105 is a high reliability varistor and MOV that is optimized for high clamping of transients up to 12kA. The device is ideal for a range of applications from communication and industrial systems, to automotive and consumer products. The device is designed to suppress high frequency transients such as ESD (electrostatic discharge) and is designed for use with transient voltage protection diodes (known as “clamper diodes”).The B72220T2251K105 is a non-linear resistor that consists of two sets of metal oxide (MOV) varistors connected in parallel. When an external electric current passes through the device, the resistance of the varistor changes instantaneously in response to the voltage. This resistance changes according to the amount of current and the voltage applied. The device can be connected directly to a circuit with the voltage connected to the B72220T2251K105’s two sets of metal oxide (MOV) varistors.The B72220T2251K105 is made of a two-layer construction of silicon rubber and zinc oxide. This combination provides superior insulation, making it ideal for applications that require high dielectric absorption ratio, high dielectric strength and low capacitive character. The device’s two sets of varistors provide a low and high voltage breakdown. The use of two varistors provides additional protection and ensures that the device can handle extreme levels of voltage surges.The B72220T2251K105 offers several advantages, such as low leakage current, high peak current, long service life, high surge current pass capability and low clamp voltage. The device is also resistant to environmental and mechanical influences, such as heat, vibration and humidity.The B72220T2251K105 is designed for a variety of applications, including automotive, consumer, communication, industrial, medical and home appliances. The device is designed to protect sensitive electronic equipment from overvoltage surges, such as those caused by lightning strikes or utility power spikes. The device also provides protection for other electronic systems, such as those found in data centers, server rooms and telecommunications systems.The B72220T2251K105 is also an ideal choice for protecting industrial systems from ESD and RFI interference. The device’s two sets of metal oxide varistors provide superior performance in suppressing both AC and DC RFI/ESD, while providing high clamping voltages. The device also provides superior protection from electrical transients for a range of electrical systems.In summary, the B72220T2251K105 is a high reliability, high performance varistor and MOV designed to protect sensitive electronic equipment from overvoltage surges and other transient phenomena. The device is highly robust and resistant to environmental and mechanical influences, making it well suited for a range of demanding applications.
