TVS - Varistors, MOVs are types of surge protection devices that protect electronic circuits from overvoltages from transients, power lines and inductive load switching. The CN1812K11G is one such device that provides protection from ESD events and overvoltage transients.

Application Field

The CN1812K11G is designed for use in various kinds of electronic equipment, such as telecom distribution, central offices, protection of sensitive semiconductor components, switching power supply, and in automotive applications. These devices can protect against electrostatic discharges (ESD) and over-voltage transients up to ±30KV and offer excellent protection.

Working Principle

The CN1812K11G uses a Metal Oxide Varistor (MOV) technology to provide protection from ESD and overvoltage transient events. The MOV works in a similar manner to traditional varistors, in that they both act as voltage-dependent resistors. However, the MOV is a much tougher device and can withstand higher voltages and higher temperatures. When a surge voltage is present, the MOV will start to act like a resistor and will reduce the voltage across the connected device, thus protecting it from damage. The CN1812K11G provides a form of “clamping” action, which reduces overvoltage and ESD events. The CN1812K11G also features an internal temperature protection circuit, which prevents the MOV from overheating in situations of high energy ESD events. In addition, the device also protects against reverse-bias, which can be a problem with traditional varistors.

The CN1812K11G is designed for easy mounting, with its lead frame, which allows for simple installation and removal. The device is also RoHS compliant and is UL listed, which ensures its reliability to withstand any kind of environment. The CN1812K11G is also compatible with a variety of common surfaces and mounting configurations, making it an easy-to-use surge protection device.

In conclusion, the CN1812K11G is an excellent choice for providing protection from overvoltage transients and ESD events. This device provides a robust protection solution for sensitive electronic equipment, while being easy to install and maintain. Its unique design and UL listing makes it an ideal solution for a wide range of applications.
