TVS - Varistors, MOVs

Transient voltage suppression (TVS) components, also known as varistors, metal oxide varistors (MOVs), and protectors, are specialized devices used to prevent voltage transients on sensitive electronic circuits. They are used on both high-voltage and low-voltage systems to protect against over-voltage and sudden power outages.These components can be used in a variety of applications, including telecommunications, automation, medical, automotive, and consumer electronics. The most commonly-used type of TVS components are metal oxide varistors (MOVs). MOVs are particularly well-suited for high-voltage protection applications due to their outstanding surge capabilities, high clamping voltage, and fast response time.One of the most popular MOVs is the B72225T4251K101. This device is ideal for applications where the over-voltage condition is expected to be transient and/or short-term. B72225T4251K101 allows a maximum continuous voltage of 8.3 V, with a peak surge voltage of 30 V. It has a maximum capacitance of 700 pF, and a maximum inductance of 0.02 mH.The B72225T4251K101 is designed to be used in applications where it will need to be constantly subjected to high surge voltages. It is able to quickly respond to sudden voltage changes, discharging the extra current before it has a chance to do any damage. The device also has a large junction capacitance, which can help safeguard against voltage transients that occur over long periods of time.The working principle behind the B72225T4251K101 is fairly simple. When the voltage on the device exceeds the specified limit, it begins to conduct current. This current is then diverted to ground or another voltage source, protecting the circuitry from the voltage transient. The device also has a built-in thermal protection feature, which helps to prevent damage caused by excessive heat.The B72225T4251K101 is a highly useful component that can protect a variety of sensitive electronics from voltage transients. It has a wide operating temperature range and is designed to handle high surge voltages, making it an ideal choice for a range of applications. With its fast response time and high peak surge voltage capabilities, the B72225T4251K101 is the perfect device for protecting sensitive electronic components from sudden voltage spikes and power outages.
