TVS - Varistors, MOVs
The V131CA40 is part of a family of electrical surge protectors commonly known as Transient Voltage Suppressors, TVSs, Varistors or Metal Oxide Varistors (MOV). This device is used to protect sensitive electronics from voltage surges both from external sources and those that may be generated internally by machinery and other electrical equipment, such as motors. The device is not limited to protecting against external sources though; it can also suppress the emitter noise generated by switching transistors, electrical motors and other electronic elements.The V131CA40 is a unipolar two-pin component that is used to absorb voltage spikes, helping to improve system reliability and providing dependable overvoltage protection. When equipped with a series resistor, the device works as a transient overvoltage suppressor and helps to protect against oscillations that may otherwise occur. It also provides an increased switching speed due to its effective clamping voltage.This device has a peak-power rating of 130 watts and a current surge of 125A, making it suitable for both industrial and automotive applications. The device is designed to be installed in a circuit near the component that requires protection, in an area between ground and Vcc, and is then connected to ground via a low-impedance point such as the circuit board frame connection or the neutral bar of a chassis.The device works on the principle of clamping and limiting the voltage overshoot of an incoming pulse. By connecting directly across two terminals, the V131CA40 works by sensing an overvoltage and then reacting by creating a low resistance short circuit path across the terminals. This reduces the over voltage to a level that will be safe for the protected component.In operation, the device works by reducing the peak voltage of a surge and diverting the generated current away from the system by switching an internal load to ground. The voltage threshold or trigger point for a positive or negative surge for the device is 18v.The V131CA40 is safe and reliable, with good stability and consistency. It has a high level of efficiency with excellent performance and long-term reliability. The device makes it easy to protect sensitive electronic components from voltage transients, improving system operation and making critical systems more reliable and efficient. The device is suitable for a wide range of applications such as computers, communication equipment, and consumer electronics.It is important to note that the V131CA40 should be used as part of an overall surge protection system. A single device, no matter how good its specifications are, cannot offer total protection. An overvoltage protection system should be designed based on a risk assessment and should include other components such as MOVs, varistors and gas discharge tubes. This will provide the user with a comprehensive solution to their overvoltage protection needs.
