Varistor, or metal oxide varistor, is one of the oldest and most widely used components in solid-state electronics. Varistors are used extensively in high voltage applications because of their ability to protect circuits from overvoltage transients. They are usually used in conjunction with smaller, surface-mount (SMT) or through-hole (THM) surge protection components such as MOVs to provide additional protection and reliability in the circuit.

V680LT100CP is a radial leaded varistor widely used in industrial applications, automotive, consumer, and telecom applications. It is intended to provide protection against overvoltage transients such as surges, lightning strikes, and surges from switching operations. The working principle of V680LT100CP is based on the volt-ampere characteristics of PTC materials (positive temperature coefficient of resistivity). It has a linear resistive characteristic, which changes its resistance dramatically with even small changes in voltage.

The V680LT100CP varistor is characterized by its high surge capability, making it ideal for protection against high transients in situations where high current pulses are present. It features a voltage range of 6-80 V, and an impedance of 8-100 ohms (25/100 μs). The recommended voltage rating for the V680LT100CP is always higher than the nominal circuit voltage to ensure overvoltage protection. It also has a high surge capability, making it suitable for everything from consumer and automotive to industrial and telecom applications.

The V680LT100CP is designed for applications that require a reliable, low-voltage surge protection solution. The device can be used to provide continuous transient protection to circuits. In most cases, the varistor is connected in parallel with a load or another component that needs protection from surges. With its high surge current capability, the V680LT100CP can provide additional protection for sensitive components, such as integrated circuits, against high voltage transients.

The device is capable of handling high levels of recurrent transients. It is triggered during overvoltage occurrences and when the voltage returns to normal level, it immediately returns back to its high impedance state. The high surge capability also makes the V680LT100CP suitable for protecting circuits from switched-mode power supplies and other noise sources, such as electro-magnetic interference. In addition, the device also offers longer life expectancy when compared to MOVs.

The V680LT100CP is also well suited for automotive applications, such as electronic fuel injection and airbag control systems, that require robust and highly reliable surge protection. Its high surge capability ensures that even if multiple surges occur, the device will remain intact and continue to protect the electronics from further damage. In addition, the device exhibits good self-healing properties, so it can be reused even after a high surge event.

In summary, the V680LT100CP varistor is an ideal choice for a wide range of high voltage applications. It has a high surge capability and a low voltage rating, making it an excellent choice for circuits that need reliable protection from voltage transients. The device also offers good self-healing properties and a longer life expectancy than MOVs, making it ideal for mission-critical and safety-critical applications that require a high level of reliability.
