TVS (Transient Voltage Suppressor) is a type of component used in the power supply circuit to suppress transients caused by voltage spike. When the voltage exceeds the breakdown voltage, it provides the current that protects the circuit from the spike. MOV (Metal Oxide Varistor) is a type of Varistor that limits overvoltage to a low-voltage shunt or clip. It is typically used for transient suppressor, surge protector, or short-circuit circuit breaker.The V275LU2P Transient Voltage Suppressor (TVS) is a dual-mode varistor and is specially designed for surge protection applications. Its two-pole varistor offers superior circuit protection and is suitable for suppressing both normal and high-energy transients. It provides the performance of a single-pole varistor on one side and a higher energy dissipation on the other.

V275LU2P application field and working principle:

The V275LU2P is a two-pole TVS designed for use in a variety of applications, including power supplies, UPS systems, data centers, and automotive electronics. The device is suitable for both normal and high-energy transients, offering superior protection to electronic equipment from fault-generated surges and power line-induced transients.

The V275LU2P has a large energy capacity of up to 2.75J, and is designed to limit the peak voltage of surges to a safe level. It provides high clamping voltage and low clamping time of up to 100V/10 nanoseconds. The device also features a patented “dual-mode” operation, where one side operates in a standard Varistor mode, while the other side operates in a high-energy Varistor mode, providing superior performance in terms of energy absorption and clamping voltage capability.

In normal operation, the V275LU2P varistor element is in the off-state, meaning that it does not conduct current. In the presence of an overvoltage, the V275LU2P element begins to conduct current, limiting the rise in voltage and dissipating the excess energy over an extended period of time. During this process, the device absorbs a portion of the energy, while the remaining energy is diverted away from the protected circuit. The V275LU2P is designed to limit the peak voltage of the surge to a safe level, and by dissipating the excess energy, it helps to protect the circuit from damage.

The V275LU2P is a highly effective two-pole varistor that offers superior reliability and protection from overvoltages, short-circuits, and other transient surges. It provides an extremely fast response time and high energy absorption in a variety of applications. By limiting peak voltage levels to a safe level, and by dissipating excess energy, the V275LU2P helps to safeguard complex electronic equipment from damage.
