TVS - Varistors, MOVs are widely used in various industries due to their ability to protect against an abnormally high voltage and electrical surges. B72214S1140K552 is an example of a device in this family, and it is a two-element bidirectional transient voltage suppressor (TVS) with a maximum peak pulse power of 4,000 W (2 x 2,000 W). The device has the capability to reduce the amplitude of an applied voltage spike and/or clamp it within a specified range.
Applications
B72214S1140K552 is often used in automotive applications due to its ability to protect against spikes. It is used for DC/DC converter input/output protection as well as protection of power supplies, motor circuits, and LED lighting. The device is also used in the medical industry to protect medical devices and monitor equipment from electrical disturbances that may result from an electrical surge or overvoltage.Working Principle
B72214S1140K552 has a breakdown voltage (V (BR)) of 14 V, and operates best with direct current applications. The device consists of two bidirectional transient voltage suppressors, each with two metal oxide varistors (MOVs). The two MOVs at the input of the transient voltage suppressor are connected in parallel. These MOVs have a high impedance to current flow under normal conditions. When an abnormal voltage spike is detected, the suppressor limits the voltage to the specified value, about 14V, after which it releases the current. The second pair of MOVs at the output is connected in series. They limit the current to a specified value, and any excess energy is dissipated as heat. The device protects against high-voltage surges in both directions, preventing them from causing permanent damage.Conclusion
B72214S1140K552 is a two-element bidirectional transient voltage suppressor designed to protect automotive, medical, home electronics, and other electronic applications from electrical surge and overvoltage damage. The device consists of two sets of MOVs connected in parallel and series to limit the voltage and current within a specified range. The device is effective at protecting against electrical surge and additional protection is typically provided by other devices.The specific data is subject to PDF, and the above content is for reference
