V140LT10CPX2855 Application Field and Working Principle

Introduction

TVS (Transient Voltage Suppressor) Varistor, MOVs (Metal-Oxide Varistor) are devices that protect circuits against transient voltages. The V140LT10CPX2855 is a bidirectional TVS varistor with a maximum breakdown voltage of 145V and a clamping voltage of 155V. It is designed to protect circuits against high voltage transients due to sources such as power surges, lightning strikes, or electrostatic discharge.

Application Field

The V140LT10CPX2855 is designed for high voltage transient protection in automotive, industrial, telecom, and consumer applications. It is especially applicable for protecting against higher voltages in automotive applications such as alternating current (AC) power adapters, and DC power supplies. It is also suitable for protecting against lightning conductors in the telecom industry.In consumer applications, the V140LT10CPX2855 can be found in electronic devices such as cell phones, computers, and game consoles. The device can also be used in dishwashers, washing machines, and other home appliances.

Working Principle

The working principle of the V140LT10CPX2855 is based on the concept of voltage division. When an overvoltage event occurs, a low value resistor connected in series to the device behaves like a voltage divider. As the voltage increases, the resistance of the protected circuit decreases, causing the voltage drop across it to decrease. As the voltage drop decreases, the voltage on the other side of the resistor is increased, thus triggering the V140LT10CPX2855 to engage and clamp the voltage to its breakdown voltage.This ensures that the circuit is protected from the overvoltage, as the voltage across the circuit is kept at a steady maximum value. The device can also be used to protect against reverse voltages and other transient voltages.

Conclusion

The V140LT10CPX2855 is a bidirectional TVS Varistor with a breakdown voltage of 145V and a clamping voltage of 155V. It is designed for protecting circuits against high voltage transients such as power surges, lightning strikes, or electrostatic discharge. The device is suitable for automotive, industrial, telecom, and consumer applications, and can be found in devices such as cell phones, computers, and game consoles. The working principle of the device is based on the concept of voltage division, ensuring that the circuit is kept at a steady maximum voltage and protected from overvoltage and transient voltages.
