Varistors, often referred to as transient voltage suppressors (TVSs), are electronic components that limit or suppress short transients on power supplies.MOVs, or metal oxide varistors, work similarly, but rely on a metal-oxide combination to suppress voltage transients. Different versions of these components are designed to work in a variety of applications and voltage ranges.The EZJ-P1V420FM is a TVS – Metal Oxide Varistor (MOV) designed to reduce the voltage differences between two points in a power supply or circuit. It is a small, low-profile package with a rated surge current of 420A, making it suitable for high levels of transient surge protection in noisy environments.The EZJ-P1V420FM is classified as an electro-luminescent electroluminescent (EL) type MOV. They are designed to absorb energy from sharp voltage transients, like those from electrical surges. The MOV is triggered by a pulse of voltage greater than its rated level and then works to limit the part of the cycle that follows the pulse.The MOVs are designed with a reverse energy rating, meaning that if the current is reversed, it will not trigger the device. The actual energy absorbed by the MOV is equal to the voltage at the device multiplied by the current as it is triggered.The EZJ-P1V420FM is designed to be used in applications such as office and factory automation, power supplies, consumer electronics, and automotive applications. It can absorb current transients from 10mS up to 2000A at 1.5/50µS, making it suitable for a wide range of applications.The operating principles of the MOV are simple: The MOV has an internal resistance that starts to increase when a transient voltage is applied at the two terminals. This increase in resistance causes the voltage growth to slow, stop, or reverse, thus breaking the circuit and protecting it from excessive voltage.The EZJ-P1V420FM also features a built-in thermal cut-off, which shuts off the MOV when it reaches a dangerous temperature. This ensures that the MOV will not be damaged due to overheating.In conclusion, the EZJ-P1V420FM is an effective and convenient device for suppressing transient voltage spikes. Its reverse energy rating and built-in thermal cut-off allows it to be used in a variety of applications, while its low-profile package makes it easy to install in cramped spaces. The EZJ-P1V420FM is a great choice for those who need to protect their circuits from sudden and intense voltage surges.
