V180CH8S

TVS, short for Transient Voltage Suppressor, is an electronic device designed to protect equipment from overvoltage pulses. MOVs (Metal Oxide Varistors) and Varistors are two of the most common types of TVS devices used in today’s electronics. The V180CH8S(2) device is a varistor type of TVS designed to protect industrial and medical equipment from overvoltage transients.

Application Field of V180CH8S

The V180CH8S is an 8-pin varistor device ideal for use in applications such as industrial, medical, and communication equipment. Its bidirectional performance provides protection from positive and negative transients in the range of 1.5 to 4.5V, and features very low capacitance levels. It has an operating temperature range of -55°C to 125°C, and can withstand a power surge up to 150V.

The device is suitable for applications where reliability and high performance are required. It is well-suited for use in transmission lines, motor drives, and for any equipment that requires protection from electromagnetic interference (EMI) or electrical fast transients (EFT). It also offers excellent surge current and soakage protection, along with reduced power dissipation.

Working Principle of V180CH8S

The V180CH8S is a bidirectional device based on Zinc Oxide varistor technology. It works by absorbing the transient energy or pulse in the form of voltage and current, and dissipating it in the form of heat. The device is designed to protect systems from overvoltage transients by providing a low impedance path for the surge current. This helps to reduce the voltage to a safe level, while still allowing the system to remain operational.

The device works by using the Zinc Oxide varistor material, along with an external resistor, to create a voltage-dependent resistance that is much lower than the normal resistance of the transmission line.When an overvoltage transient occurs, the voltage across the device increases dramatically, causing the current to increase to a level that can be safely dissipated. As the voltage across the device decreases to safe levels, the current also decreases and the device returns to its normal state. This process occurs in microseconds, allowing the system to remain operational during the surge.

The V180CH8S is also designed to protect against adverse environmental conditions, such as vibration, temperature, humidity, and corrosion. It is RoHS compliant and can be used in extreme temperatures down to -55°C, making it suitable for use in outdoor and other high-temperature applications.

The V180CH8S is an effective device for providing protection from overvoltage transients in industrial, medical, and communication applications. Its bidirectional performance and low capacitance levels help to protect against EMI and EFT, while its surge current and soakage protection help to provide reliable operation in challenging environments.
