TVS - Varistors, MOVs, play an important role in the circuit to help to shunt excess voltage away from sensitive electronics and equipment. A typical type of varistor is the V300LS2P, which is a 240 V AC / DC protection varistor that has a clamping voltage of up to 300 volts.

The design of the V300LS2P uses two-level metallized zinc oxide circuits and is constructed in an epoxy-filled cylindrical case with glass fibers. It is designed to syphon away overvoltages and perform effective and reliable surge protection. The varistor is tin coated to help protect it against corrosion and oxidation.

The V300LS2P is suitable for use in applications where the equipment needs to be protected from transient overvoltage caused by lightning, ESD, high voltage transients and motor switching. The device also offers low clamping voltage, extremely low leakage current and high peak current dissipation. It is designed to be fast acting and is widely used in power supplies, air conditioners, lighting, telecom equipment, machinery and many other high-frequency components.

The working principle behind the V300LS2P is that it will shun unwanted transients away from the equipment it is protecting. The current flow through the device will be limited as the voltage across the transient increases, which will reduce the amount of current that can flow through the device and provide effective protection.

When the transient voltage increases to a sufficient level, the varistor will take on a current limiting function and allows more current to flow through the device. This in turn will reduce the amplitude of the transient voltage, and effectively limit the voltage that is exposed to the protected equipment.

In order to ensure that the V300LS2P has enough energy to absorb the unwanted transient overvoltage, it should be connected in series with the protected equipment. This configuration provides an additional clamping voltage, which can help to protect the equipment during peak transient conditions.

The V300LS2P is an effective and reliable way of providing protection of sensitive electrical equipment from transients that can cause the equipment to fail or be damaged when they occur. By channelling the unwanted transients away from the protected equipment, it can help to prolong the life of the equipment and protect it from costly damage.
