TVS, or transient voltage suppressors, are electronic components that help protect against voltage transients—sudden, excessive voltage spikes that occur in electronic devices. Among the various TVS components, Varistors, MOVs, and ROV14H151K-2 are some of the most popular. In this article, we will focus on the ROV14H151K-2 and discuss its application fields and working principle.

ROV14H151K-2, or resistance-based overvoltage protection, is a circuit protect device designed to protect electronic devices and circuits from damage from electrical over-voltages. It is an ideal component for products that require high reliabilty and performance. The main application fields for the ROV14H151K-2 include Automotive, Industrial, IT infrastructure, Medical and Telecom. It is suitable for automotive electronics, including automotive ignition systems, dashboards and audio systems; industrial equipment such as PLC controllers, power supplies, audio amplifiers and motor drives; IT infrastructure such as servers, routers and switches; medical devices such as EEG monitors and X-Ray machines; and telecom equipment including PBXs, routers, and DSL modems.

The ROV14H151K-2 is a nonlinear variable resistor that uses a combination of resistive and capacitive elements to limit the amount of voltage that can be applied to a circuit. When the voltage across the device exceeds a set threshold voltage, the nonlinear resistance of the device quickly increases, limiting the amount of current that can flow through the device. This helps protect the protected component from damage due to overvoltage conditions.

In addition, the device also has a built-in current limiter that can further protect the circuit from damage due to overcurrent conditions. The current limiter works by sensing the current that is present in the circuit. If the sensed current exceeds a certain limit, the device will quickly reduce its own internal resistance, thus limiting the amount of current that can flow through the device. This helps protect the protected circuit from damage due to overcurrent.

In conclusion, the ROV14H151K-2 is a highly versatile component that can be used to provide overvoltage and overcurrent protection in a wide variety of applications. Its combination of nonlinear variable resistors and current limiters makes it well-suited for applications where reliability and performance are essential. Its application fields range from automotive to industrial, IT infrastructure to medical, and telecom to consumer durables, making it one of the most widely used TVS components for circuit protection.
