A Transient Voltage Surge Suppressor (TVS), also commonly referred to as a voltage-variable suppressor or, more plainly, a varistor, is an electrical device used to protect a circuit from excessive transients and surges. One of the most commonly used TVS is the V230LT4, and it is used for a variety of applications, such as overvoltage protection, line transients, and EMI/RFI protection.

The V230LT4 is an unidirectional metal oxide varistor (MOV) that is designed for insertion in an IEC61000-4-5 certified cable set or surge protectors. It is designed to dampen electrical transients and surges that cause overvoltage conditions. It is a simple, robust, and reliable device that can be used in a variety of applications and industries.

When a surge or transient passes through the device, the V230LT4 works by dissipating the energy away from the protected circuit. It has several advantages over other types of voltage-variable suppressors, such as higher surge currents, higher clamping voltage, lower reverse leakage current, and a lower power dissipation.

The V230LT4 is a 4-pin single-phase device. It is rated for a maximum surge current of 20A. The device\'s maximumvoltage rating is 500V. The insulation resistance between terminals is at least 100 gigohms at 500Vdc. Its differential-mode attenuation is -40dB. The device has a very low reverse leakage current of less than 10uA.

The working principle of the V230LT4 is based on the zinc oxide element. The device is made up of a temperature-stabilized, high-purity, non-crystalline zinc oxide element, which acts as a surge absorber. This element is encased in a high-grade flame retardant epoxy resin that helps protect the device from external environmental factors.

When an overvoltage situation occurs, the zinc oxide element within the V230LT4 clamps and dissipates the energy by providing a high level of resistance. This resistance opposes the surge current, greatly reducing its amplitude. This reduces the current amplitude and allows the device to operate within its specified operating parameters.

The V230LT4 is an ideal voltage-variable suppressor for applications that require overvoltage protection, line transients, and EMI/RFI protection. Because of its robust, reliable design and high surge-current handling capabilities, it is suitable for use in a wide variety of applications.

In summary, the V230LT4 is a very reliable, robust, and versatile voltage-variable suppressor that is widely used for a variety of applications, such as overvoltage protection, line transients, and EMI/RFI protection. It is highly rated for its ability to handle high surge currents and is encased in high-grade flame retardant epoxy resin to protect it from environmental factors. The working principles of the device are based on the zinc oxide element, which clamps and dissipates the energy by providing a high level of resistance.
