V320LS20A is a kind of Thyristor-Protected Varistor. It is a combination of a relationship between resistance and voltage that govern and protect side drive devices such as TVS (transient voltage suppressors), MOVs (movs) and unijunction transistors (UJTs). It has positive temperature coefficient so it can offer excellent protection against over-voltage, surge current and switch-on voltage.

The application field of V320LS20A is broad and includes automotive, marine, aerospace and industrial applications. In automotive, it is used to protect the vehicle components from environmental influences such as over-voltage, under-voltage, transient voltage and others. It is also suitable for protecting electrical circuits from voltage transients in both amateur and professional marining fields, such as medium to large boats and also aircraft. In industrial applications, it offers protection against voltage spikes, hangovers, voltage-overload and short circuiting.

The general working principle of V320LS20A is based on the behavior of its components. These components include a thyristor, which is an electronic semiconductor device that has a three-terminal connection for turning on and off electrical current. A varistor is basically a resistor with a non-linear resistance-voltage characteristic, meaning that its resistance changes with voltage. It is used in electronic devices to protect the components from surges or spikes in the voltage. Lastly, a MOV (metal oxide varistor) is a non-linear resistive component which provides protection against voltage spikes or surges, thereby safeguarding against hazardous electric shock, excessive current and potential fire hazards.

V320LS20A also incorporates temperature compensation to improve its performance. This is accomplished by using a thermistor, which is another semiconductor component with a unique temperature-dependent resistance. The thermistor is installed in the device and its resistance adjusts itself according to the temperature changes, thereby ensuring the protection against over-voltage as well as under-voltage. In addition to temperature compensation, V320LS20A also provides protection against electromagnetic interference

V320LS20A is an excellent example of a Thyristor-Protected Varistor that can be used in a wide variety of applications. It combines the protective capabilities of MOVs, thyristors and varistors with temperature compensation, surge current protection and other features to ensure effective protection against voltage spikes and transient voltage. It can be used in various automotive, marine, aerospace and industrial applications
