TVS (Transient Voltage Suppression) is a type of solid-state device used to protect sensitive electrical and electronic circuitry from damage caused by transient or surges in voltage. Varistors, MOVs (Metal Oxide Varistors) are specialized components designed to protect sensitive electronic systems from damaging transients, surges, or spikes in voltage. To understand more about VE09M00500KDA, let\'s take a closer look at its application fields and working principle.

Application Field

VE09M00500KDA is an integrated device specifically designed to protect power systems against transient overvoltage. It is mainly used in industrial instruments, communication equipment, factory automation systems, appliances, medical equipment and other electrical and electronic systems and circuits from over-voltage. It is designed to be mounted directly onto the board and offers a protection rating of 9V.

Working Principle

VE09M00500KDA is made up of a surge protection diode, a transient voltage suppressor (TVS), and a metal oxide varistor (MOV). It works by diverting the excess transient or surge voltage away from circuit components, thus protecting them from potential damage. The TVS is triggered when the voltage exceeds its breakdown voltage, and the MOV absorbs any residual energy. This allows VE09M00500KDA to protect the system from transient overvoltages of up to 9V. The device is also designed to automatically reset itself after the transient voltage has been successfully dissipated.

VE09M00500KDA also features a low leakage current and minimal capacitance for tailored performance, ensuring reliable protection for delicate circuit components. It is also designed to meet IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) standards, making it suitable for use in harsh industrial environments where surges and transients are common.

In summary, VE09M00500KDA is an integrated device designed to protect power systems against transient overvoltage. It features a surge protection diode, a TVS, and a MOV, and is designed to withstand overvoltage up to 9V. The device is also designed to automatically reset itself after it has successfully dissipated the overvoltage, and it meets IEC standards, making it suitable for use in industrial environments.
