The V18MLE0805T is a device generally classified as either a Transient Voltage Suppression (TVS) or a Metal Oxide Varistor (MOV). It is generally used to protect circuit components from inrush currents and overvoltage transients by providing an alternative route for the current. In addition, some of the other applications for this device include protection of critical control circuitry and data bus lines from overvoltage transient events.

The V18MLE0805T is a TO-220 package type MOV with 18mm lead spacing and an insulation rating of 800 volts. It has an epoxy encapsulated and 2.8 mm diameter ceramic tube design. These features make it well-suited for use in high voltage applications. Its internal packing material and epoxy insulation provide both insulation and light protection against mechanical vibration. The V18MLE0805T also has an operating voltage range of 18 to 28 volts and a rated voltage of 24 volts.

The working principle of the V18MLE0805T is similar to that of a varistor or a Metal Oxide Varistor (MOV). When the device is exposed to an overvoltage condition, it effectively acts as a voltage-dependent resistor, allowing current to pass through rather than just absorbing the energy like a capacitor would. This allows for the overvoltage to pass through the device without damaging the underlying components. The varistor is made up of a zinc oxide material, which has a non-linear resistance. This non-linear characteristic can help to protect against both high and low voltage surges, as well as spikes or transients.

The V18MLE0805T is typically used to protect circuits and components from overvoltage transients or excessive inrush currents. It is used in a variety of applications, including consumer electronics, communications, industrial control systems, medical, automotive, and test and measurement equipment. It is also used for protection within low and medium voltage AC and DC power supply systems. Its surge suppression capabilities make it well-suited for use in high frequency switching circuit applications, including in UPS systems.

The V18MLE0805T is a versatile device that can be readily incorporated into existing systems or be used in new designs. Its unique combination of electrical and mechanical properties, as well as its high surge current ratings, make it well-suited to a wide variety of applications. In addition to being reliable and easy to install, the V18MLE0805T offers superior surge suppression performance thanks to its combination of electrical and mechanical properties.
