TVS (Transient Voltage Suppressor) devices provide an electric protection for power circuits and digital circuits from the dangers of spikes in voltage. Varistors, also referred to as a voltage-dependent resistor (VDR), are one type of these protection devices. They are also known as Metal Oxide Varistors (MOVs), and their application field and working principle both depend on the characteristics of their construction.

VE17M00251KED is a model of metal oxide varistor, and it has the following characteristics: withstanding voltage is 1700V, rated voltage is 250V, and operating temperature range of -40°C to 85°C.

Metal oxide varistors are semiconductor devices which consist of quadrilateral granules made from a mixture of zinc oxide and other metal oxides. The material has two types of grain structure; n-type and p-type. In an applied reverse electrical field, the zinc oxide grains repel each other, increasing the distance between them. This means that the resistance of the material is significantly reduced. When the voltage applied to a varistor is below its rated value, the device has very high impedance (<10 megaohms). At or above its rated voltage, the granules become so close that the zinc oxide material behaves like a conductor. Thus, the resistance of the device suddenly drops to a very low level (20-30 ohms).

VE17M00251KEDvaristors, as with other varistors, are used mainly as protection devices. They are ideal for use in suppression of overvoltage transients, and can withstand continuous operation at rated DC voltage. They can also absorb large pulse power and have a low clamping voltage.

VE17M00251KEDcan be applied to the protection of small current circuits against high transient voltage in industrial and power equipment, communication systems, household appliances, computers, and automotive circuits. Additionally, they have protection functions for DC power supplies, transient power line surge suppression, energy saving lighting, power factor correction, EPS, UPS and other power system devices.

In conclusion, VE17M00251KEDis a metal oxide varistor that can be used in suppression of overvoltage transients. It has a withstanding voltage of 1700V, rated voltage of 250V, and must be operated within the temperature range of -40°C to 85°C. It is mainly used for the protection of small current circuits against high transient voltage, and it can be applied to industrial and power equipment, communication systems, household appliances, computers, and automotive circuits.
