TVS - Varistors, MOVs

Varistors, also known as voltage-dependent resistors (VDRs), metal oxide varistors (MOVs), or transmission line interface devices (TLID), are electrical components used to protect circuits from transient overvoltage and to limit voltage surges. The V39ZU1P is a voltage-controlled (non-metallic) varistor, designed for use in Smart Grid applications, and is rated for a maximum operating voltage of 700V.The V39ZU1P is a non-linear device made of a zinc oxide ceramic material; it has a small size and is ideal for space-constrained designs. It has a wide operating temperature range (-40°C to +125°C) and a low temperature drift. It is configured with two electrical connection points, which are typically connected to the control circuit and the protected circuit. The varistor has a large energy rating, allowing it to be used in high voltage applications.The V39ZU1P is an effective device for the protection of control circuits and subparts from overvoltage and overcurrent conditions. The device\'s fast response time helps to protect against fast-rising voltage surges, while its high breakdown voltage and clamping capabilities ensure that the circuit is not damaged from sudden voltage spikes. It is also used to mitigate transients due to switching of high current load, ensuring that the overall system is not damaged from inrush current.The V39ZU1P works as an electrical circuit breaker. It is a two-terminal device and can be configured as either an open circuit or a shunt. In open circuit configuration, the varistor provides an open circuit between the control circuit and the protected circuit. This configuration ensures that the overvoltage is shunted away from the main circuit and protects it from a high voltage surge. In shunt configuration, the varistor acts as a voltage-dependent resistor, providing a path for excess current to flow to the ground and away from the protected circuit.The working principle of the V39ZU1P is based on the fact that its resistance is dependent on the applied voltage across it. When the applied voltage is low, the varistor has a very low resistance, but as the voltage increases, its resistance increases significantly. This allows for effective protection from overvoltage and overcurrent conditions.The V39ZU1P and other varistors can be used in a number of different applications including consumer electronics, industrial control systems, energy-management systems, and Smart Grid applications. It is also used as a surge suppressor in AC power sources and in DC circuits. It is also used to limit inrush current caused by sudden switching of load. The V39ZU1P is particularly suitable for use in high-voltage applications due to its high energy rating.The V39ZU1P is an effective device for overvoltage and transient protection in control circuits and is suitable for use in a variety of applications. It features fast response times and a high energy rating, making it ideal for high voltage applications. It is also compatible with a wide range of operating temperatures and has a low temperature drift. The V39ZU1P is a versatile and cost-effective solution for protecting circuits from transient overvoltage and overcurrent conditions.
