Transient voltage suppressors (TVS) and metal oxide varistors (MOV) are the two main types of components used for electrical surge suppression. The TMOV14R250M is an example of a metal oxide varistor specifically designed to protect electronic devices from voltage transients, such as over voltages, induced by lightning strikes, switching operations, or electric arcs.
What is an MOV?
An MOV or metal oxide varistor is a solid-state surge suppressor designed to protect sensitive electronic devices from transient voltage spikes. It is a nonlinear, voltage-dependent resistor that is often constructed from materials such as sintered zinc oxide or tantalum pentoxide. These components are electrostatic spark gaps that can clamp high voltage surges or overloads in order to protect the downstream device.TMOV14R250M
The TMOV14R250M is a particular type of metal oxide varistor designed for high reliability applications. This component is an ultra-robust MOV designed to protect sensitive circuits from transient overvoltage events in the range of 14 to 16 V DC. This component can handle high pulse peak currents up to 1,000 A, and has a fast response time to electrical transients in just a few nanoseconds.Application Field
The TMOV14R250M is suitable for a range of applications in wide range surge suppression, such as automotive, electrical, consumer electronics, power side and construction and elevators. Its applications include power supply and signal lines in data communication or other electronic systems. This component also has a broad temperature range, allowing it to be used in both cooled and hot environments.Working Principle
The TMOV14R250M operates by utilizing the metal oxide across its internal electrodes. This metal oxide works in such a way that when a voltage exceeds the rated value of the device, the metal oxides break down, diverting the electricity away from the load connected downstream in order to protect it from damage. When the voltage transient has passed, the resistance of the MOV returns to its normal state, ready to absorb the next surge.Conclusion
The TMOV14R250M is a type of metal oxide varistor designed to protect sensitive electronic systems from voltage transients, providing robust protection against surge conditions. It is suitable for a range of applications, and its working principle is based on the breakdown of the metal oxide between its internal electrodes.The specific data is subject to PDF, and the above content is for reference
