A varistor is a voltage-dependent variable resistor that limits the voltage applied across the device. Varistors are often known as transient-voltage-suppression (TVS) devices due to their ability to handle transient voltage spikes and regulate the voltage across the device. The V275LT2 is a type of TVS device and is used in a variety of applications, from protecting against dangerous voltage spikes in telecoms and energy systems to safeguarding electronic equipment from voltage steps in home appliances.

Various parameters must be considered when selecting a TVS device for an application, such as peak power rating, hold-down voltage, energy absorption, and dynamic resistance. The V275LT2 has many features that make it well suited for a range of applications, including a high peak power rating of 880 Watts, a hold-down voltage of 30-45 volts, an energy absorption rating of 270 joules, and a dynamic resistance of 0.25 Oms.

The V275LT2 also boasts an impressive pulse power handling capability with peak current ratings of 10,000 amperes. This feature helps to protect against fast rising, high energy transients such as lightning strikes, line disturbances, and switching transients. The device has also been designed with a rugged ceramic package that has excellent thermal dissipation, making it well suited for high temperature applications.

Another key feature of the V275LT2 is its low capacitance which helps to provide excellent high frequency performance. Low capacitance helps to reduce EMI (electromagnetic interference) and RFI (radio frequency interference) effects, ensuring optimum signal transmission quality is maintained. The combination of these features makes the V275LT2 an ideal option for applications such as suppression of RF and ESD (electrostatic discharge) pulses.

The V275LT2 is a unidirectional TVS device, meaning the applied voltage must always flow in the indicated direction for correct operation. The device has two electrodes which must be properly installed for its effectiveness and operation. When the applied voltage exceeds the hold-down voltage rating, the device begins to conduct, acting as a bridge between the two electrodes to dissipate damaging transient voltage.

In summary, the V275LT2 is an efficient, durable TVS (transient-voltage-suppression) device that is suitable for a wide variety of applications due to its impressive features and rugged properties. Its high peak power rating, hold-down voltage, pulse power handling capability, thermal performance, and low capacitance make it an ideal choice for protecting vulnerable electronic equipment and circuits from voltage spike damage.
