TVS - Varistors, MOVs

The V14MLA0805LWH is one of the newer models of TVS (Transient Voltage Suppressor) varistors / MOVs (Metal Oxide Varistors). A TVS is a non-volatile device designed to protect electrical and electronic circuits from transient (sometimes called transient overvoltage) voltages. In its simplest form, a TVS is a capacitor-diode-resistor combination that is designed to shunt a peak voltage away from sensitive components.

The V14MLA0805LWH is designed to limit transients to a maximum voltage of 14V, with a rated clamping voltage (Vc) of 12.3V. It also has a response time of 0.1 nanoseconds, which can help protect high speed circuits such as firewire and USB 3.0. Furthermore, it is rated for a surge current of 1kA(8/20μs).

This TVS is most commonly used in automotive and industrial applications, such as power supplies and battery charging systems, high speed digital circuits, and data lines. It can help protect sensitive components from transient voltages and counterbalances large current flow during circuit start-ups. Its rated surge current capacity makes it ideal for automotive applications which are often subject to large current spikes.

The V14MLA0805LWH works by providing a low impedance path to ground for transient voltages. When the device is exposed to a voltage greater than its rated clamping voltage, an internal electrostatic discharge (ESD) diode triggers, which shunts the surge away from sensitive components. An internal resistor then dissipates the energy of the surge as heat.

This type of device is designed to be placed in series with the power supply. This way, when a transient occurs, the TVS will shunt it away from sensitive components, limiting any damage. It should be noted, however, that in some cases the TVS might be damaged itself if it is exposed to too high of a voltage or too large of a surge current. Therefore, care should be taken when selecting the proper device for a given application.

The V14MLA0805LWH is a versatile device that can provide reliable protection for a variety of applications. Its fast response time and high surge current rating make it ideal for automotive and industrial applications. Furthermore, its low profile package makes it easy to integrate in high speed digital circuits or data lines.
