ERZ-U21JP162H Application Field and Working Principle

TVS - Varistors, MOVs are devices used to protect various electronic components from fast transient voltage spikes. They are widely used in industrial, automotive, medical and consumer applications. The ERZ-U21JP162H is a device with excellent electrical characteristics and reaction rate to voltage peaks.

Electrical Characteristics

The ERZ-U21JP162H has a nominal clamping voltage of 21V and peak pulse voltage of 162V. It is rated for a working current of up to 300mA and pulse current up to 1.45A. It also has a superior capacitance of between 22pF and 25pF and an AC breakdown voltage of 6.5V. These characteristics make it an ideal choice for a wide variety of applications.

Applications

The ERZ-U21JP162H is suitable for use in a variety of circuits and electronic components. It can be used in AC/DC circuits to protect against voltage surges caused by lightning, electrostatic discharge and power crosses. It can also be used in automotive circuits to protect the vehicle and passengers from electrical shocks. It is also often used in consumer electronics to protect against power surges and voltage spikes.

Working Principle

The ERZ-U21JP162H works on the principle that an electric current in the presence of a voltage will cause an electric field to be generated. When the voltage exceeds the maximum rating, the electric field will cause electrons to flow, resulting in a charge neutralization of the transient voltage.This process can be explained more simply with the analogy of a water balloon breaking. When a balloon is over-inflated, the pressure inside is too high and the balloon bursts. In the same way, when a voltage spike is detected by the ERZ-U21JP162H, the charge will disperse through this device, resulting in a neutral charge and protecting the circuit from damage.

Conclusion

The ERZ-U21JP162H is a versatile, reliable and cost-effective device for protecting electronic components and circuits from transient voltage spikes. Its excellent electrical characteristics and reaction rate make it an ideal choice for a variety of applications, ranging from industrial to automotive and consumer applications. Its working principle allows it to quickly and effectively disperse any overvoltage, protecting the circuit from damage.
