TVS (Transient Voltage Suppressor) are protection devices used to protect circuits from overvoltage and high-energy transients. They are commonly used to protect sensitive electronics, such as smartphones, computers, microcontrollers, and other electronic components. Varistors, also referred to as Metal Oxide Varistors (MOVs), are a type of TVS most commonly used in commercial applications. The V420LT20CPX2855, a 650-V surge-rated MOV, is a widely used varistor that offers excellent protection from overvoltage and high-energy transients.

The V420LT20CPX2855 is comprised of two parts – the MOV core and the overvoltage protection element. The MOV core acts as an impedance limiter, and it is mainly responsible for absorbing and dissipating high-energy transients. On the other hand, the overvoltage protection element acts as a circuit breaker and prevents overvoltage from damaging sensitive electronics.

Due to its robust construction and excellent surge current capability, the V420LT20CPX2855 is well suited for a wide variety of applications. It has been found to be effective in protecting sensitive electronics in industrial applications, such as power supplies, circuit boards, transformers, motor drives, and other electrically charged and high-voltage equipment. The V420LT20CPX2855 is also commonly used in automotive applications, such as in alternators, spark plugs, body control modules, and more.

The V420LT20CPX2855 has a peak surge current rating of 4000A. This rating ensures that the device can effectively dissipate and absorb high-energy transients without causing damage to the protected electronics. The device also prevails in harsh environments due to its superior flame retardant rating (UL 94V-2).

In terms of design, the V420LT20CPX2855 varistor has a unique, four-layer construction. It is composed of a ceramic inner core, a graphite end plate, a Zinc Oxide disc end plate, and a tinned copper (electroplated) terminal contact. The four-layer construction offers excellent heat dissipation, allowing the device to remain cool even under heavy surge current applications.

The V420LT20CPX2855 also offers superior stability and increased reliability compared to other surge-rated MOVs. This is due to the varistor’s construction, which features a series of dissipating elements that help to absorb the energy from high-powered transients.

In summary, the V420LT20CPX2855 MOV is a widely used varistor and offers excellent protection from overvoltage and high-energy transients. The device is well suited for a wide variety of applications, such as power supplies, circuit boards, transformers, motor drives, automobiles, and more. It offers superior stability and reliability compared to other surge-rated MOVs. Additionally, it is made with a four-layer construction that allows it to remain cool even under heavy surge current applications.
