TVS - Varistors, MOVs are devices designed to protect circuits from electrical overstress, such as voltage spikes and transients. The V275SM20 is a very common Voltage-Dependent Resistor (VDR) type of TVS. This particular type of TVS is designed to handle high overvoltage conditions.

The V275SM20 has an extended voltage range of 280VDC and can handle transient voltages of up to 8000V. It also features a low internal capacitance, which makes it suitable for use in high-frequency applications such as computer and telecom equipment. The device is also designed for low inductance and high clamping current. The overall design of the device allows for a high surge current rating of up to 275A.

The working principle behind the V275SM20 is fairly simple. When excessive voltage is applied to the device, it begins to expand its size. This results in increased resistance and clamping voltage. The device, however, is designed so that it can handle high-level surges without breaking down or damaging equipment. The expanded size also helps to dissipate the excess voltage.

In terms of applications, the V275SM20 is typically used in consumer electronics, computer equipment, communication systems, power supply and distribution circuits, and other applications requiring surge protection. It is also commonly used in medical devices and other sensitive equipment. It is often used to protect sensitive circuits from over voltage surges, spikes, and transients.

In addition to its protection capabilities, the V275SM20 also has a high breakdown voltage of up to 30,000V. This allows it to dissipate a large amount of energy without failure. This makes it particularly well-suited for application in harsh environments or for use with very high-voltage power systems. It is also an excellent choice for applications in which a high level of protection is required while also maintaining a low clamping voltage.

Overall, the V275SM20 is an excellent choice for a variety of applications, as it is designed to handle high overvoltage conditions and dissipate large amounts of energy without failure. Its high breakdown voltage, low inductance, and high clamping current make it well-suited for use in consumer electronics, computer equipment, communication systems, power supply and distribution circuits, and other applications requiring surge protection. Additionally, its design and construction make it ideal for use in harsh environments or with very high-voltage power systems.
