Transient voltage suppressors (TVS) are components that provides protection against voltage transients, and are used to safely discharge or limit the surge current. Metal oxide varistors (MOVs) and non-metal thermistors (also known as varistors) are commonly used to protect sensitive electronic components from potential power surges. The ROV14H471K-2 is a common type of varistor produced by several manufacturers. It is a “surface mount” device, meaning it is designed to be installed directly to the circuit board with solder and no additional parts like pins. In this article, we will discuss the application field and working principle of the ROV14H471K-2.

The ROV14H471K-2 is a voltage-dependent resistor (VDR) designed to protect components from power surges. It has a rated voltage of 14V and an operating temperature range of -55°C to 125°C. It is designed to protect circuits from high voltage and transient current surges with peak currents from 50A to 500A and peak voltages from 8V to 20V. It can also withstand up to 150A of reverse leakage current. This wide range of ratings makes it suitable for a multitude of applications, such as automotive, machine control, factory automation, and industrial and commercial products.

The working principle of the ROV14H471K-2 is based on the properties of metal-oxide varistors (MOVs). MOVs work by using the principle of voltage-dependent resistor (VDR) in which the resistance of the device changes based on the applied voltage. The resistance decreases as the voltage increases, allowing for the passage of higher currents and protecting against surges. The ROV14H471K-2 incorporates these properties, offering protection against transient voltage surges and peak currents. Additionally, the device has a fast response time and low leakage current, allowing for greater efficiency when protecting against surges.

The ROV14H471K-2 is a great option for providing reliable surge protection in a wide range of applications. Its low leakage current, high clamping voltage, and fast response times make it suitable for protecting against voltage transients in automotive, industrial, and commercial applications. Whether you need to protect against static electricity or power surges, the ROV14H471K-2 can help you achieve reliable protection for your circuit.
