TVS (transient voltage suppressor) devices can be used in a variety of applications, from protecting against power surges in power systems to protecting against electrostatic discharge (ESD) in electronic components. Varistors, MOVs (metal oxide varistors), and Zener diodes are all types of TVS devices, each with its own unique characteristics and application fields. Varistors and MOVs are both used for surge protection, however, they differ in construction and application. Zener diodes are used for regulating the voltage in power supply circuits. The V18MLA0805LNH is a metal oxide varistor (MOV) and is used in applications ranging from power line surge protectors to signal protection for electronic components.The V18MLA0805LNH is a disk-shaped ceramic capacitor with zinc-oxide discs in a resin-encased envelope. It has a cylindrical base and probes for connecting to a circuit, and is rated for 8 Amps. The V18MLA0805LNH is designed to provide surge protection up to 250V and is rated for 1,500A of peak surge current.The working principle of a MOV is an application of the semiconductor diode. When a voltage higher than its threshold level is applied to its terminals, the MOV is essentially \'on\'. In this \'on\' state, the MOV acts as a conductor, allowing current to flow easily between its terminals. When the voltage drops below the threshold level again, the MOV switches \'off\', blocking current flow.MOVs are specifically designed to protect against transient voltage surges, such as those caused by lightning strikes, motor starts, or electrostatic discharges. They operate by clamping the voltage and dissipating the surge energy as heat. The MOVs ability to clamp down high voltage spikes means that it can be used in a variety of applications, including voltage regulation, signal protection, and surge protection.MOVs are commonly used in power line surge protectors, signal protection for electronic components, and power supplies as protection against over-voltage. They are also used in many industrial and commercial applications, such as power conditioning and motor control. In these applications, the MOV helps to protect sensitive equipment from damage and improve system reliability.In summary, the V18MLA0805LNH is a metal oxide varistor (MOV) and is used in applications ranging from power line surge protectors to signal protection for electronic components. The MOV’s ability to clamp down high voltage spikes makes it an ideal choice for applications where surge protection is necessary. It works by clamping the voltage and dissipating the surge energy as heat, and can be used in a variety of applications including power line surge protectors, signal protection, voltage regulation, and in power supplies as protection against over-voltage.
