TVS, which stands for Transient Voltage Suppressors, are used to protect sensitive electronic devices from damage due to over-voltage transients. Such transients can be generated by lightning bolts, motors, power spikes, or any other difference in electrical potentials. A varistor is a type of TVS component that is used to reduce over-voltage transients. When the voltage rises above a certain level, the varistor responds rapidly to reduce the voltage and protect the device. MOV - 07D180K is a type of varistor and it is a highly reliable, cost-effective solution for applications requiring transient over-voltage protection.

MOV-07D180K Application Field and Working Principle

MOV-07D180K is capable of handling peak voltages up to 180 volts (V). It is mainly used in overvoltage protection for electronic circuits, including DC power supplies, computer main boards, power modules, relays, switches, and LEDs. The component has a low discharge current and a low thermal resistance, making it a good choice for supplying power and safety protection in high-power applications. It is also suitable for inrush current limiting applications and is commonly used to protect sensitive electronic components like transistors, vibrators, and solenoids.

The working principle of MOV-07D180K is based on a nonlinear metallic oxide as its main component. Upon sensing the excess voltage, the component quickly begins to conduct and reduce the voltage to an acceptable level. When the voltage across the component is lower than the specified voltage, the resistance of the component increases. This process is continuous and provides steady protection against transient overvoltages.

The MOV-07D180K has a temperature coefficient of -19%, meaning it increases its resistance with decreasing temperature. This feature ensures that the device will always be operational and ready to respond to excess voltages. Additionally, the MOV-07D180K has a high peak current capability of up to 1500mA, ensuring the device can handle short-term over-voltage events. It is also certified by UL 94V-0, meaning it can withstand high temperatures and has passed safety tests.

Conclusion

MOV-07D180K is a highly reliable and cost-effective TVS component for applications requiring transient over-voltage protection. It has a peak voltage rating of up to 180 volts, a high peak current capability of up to 1500mA, a low discharge current, and a temperature coefficient of -19%. The device is capable of withstanding high temperatures and has passed safety tests. MOV-07D180K is suitable for applications such as DC power supplies, computer main boards, power modules, relays, switches, and LEDs, as well as inrush current limiting applications.
