About Varistor

Varistor, referred to as MOV, is a voltage-sensitive nonlinear overvoltage protection semiconductor component. In order to adapt to the space size requirements of equipment miniaturization and meet the needs of functional upgrades, power supply, battery management and dedicated system functions all require highly integrated advanced solutions. These are major issues that should be solved for successful consumer electronics system design. . How to improve the circuit protection level of consumer electronics products? Can overvoltage device varistors be used for surge protection in consumer electronics? The working principle of the varistor is that it has high interference when there is no instantaneous overvoltage, but its impedance will continue to decrease as the surge current and voltage increase, and its current and voltage characteristics are strongly nonlinear.

What is the function of varistor?
The response time of the varistor is ns level, which is faster than the air discharge tube and slightly slower than the TVS tube. Generally, its response speed can meet the requirements for over-voltage protection of electronic circuits. The junction capacitance of a varistor is generally in the order of hundreds to thousands of Pf. In many cases, it is not suitable to be directly used in the protection of high-frequency signal lines. When used in the protection of AC circuits, its large junction capacitance will increase leakage. Current needs to be fully considered when designing protective circuits. The flow capacity of the varistor is larger, but smaller than that of the gas discharge tube.

Description:

The 07D series radial leaded varistors provides an ideal circuit protection solution for lower DC voltage applications by offering higher surge ratings than ever before available in such small discs.
The maximum peak surge current rating can reach up to 1.75KA (8/20 μs pulse) to protect against high peak surges, including indirect lightning strike interference, system switching transients and abnormal fast transients from the power source.

Features:

Applications:

Power supply systems, surge suppressors, security systems, motor protection, automotive electronic systems, household appliances etc
