1N3890AR is a widely used single rectifier diode. It\'s mainly applied in electronic circuit, rectifier, charger and other related fields. With some advantages,1N3890AR has typical reverse voltage drop from 600 to 800 volts and average forward current from 1 to 8 A. It\'s often used as rectifier, switch and also serves as protection device in electronic equipment.

The working principle of 1N3890AR is quite simple. When the external power supplies positive current to the anode of the diode, it\'s going to conduct current to the cathode. And the anode-cathode current flows in the forward direction at this moment. On the contrary, the externally supplied negative current to the anode of the diode, it will block the current from flowing to the cathode side due to the higher reverse potential than potential on the anode side, so that the current cannot outflow from the anode.

The reverse breakover voltage is an important parameter of the 1N3890AR. It means the minimum voltage across the anode and cathode that can make the diode conduct current. However, the allowed maximum reverse voltage is also an important parameter of the diode, since it can make sure the breakdown voltage to a proper leven. Generally, the proper value of the breakover voltage should be between 600-800 volts.

1N3890AR is widely used in various fields. It\'s mainly used as a rectifier in AC-DC power supply, switch on or off device in electronic circuit, power supply voltage stabilization etc. Usually, it is applied in automatic spraying systems, welding equipment, battery chargers, motor controller, and other fields.

How to identify and select a proper 1N3890AR diode? First, the reverse peak voltage should be in line with the diode\'s working principle. Different types of 1N3890AR diodes have different working voltage range, so the user should select an appropriate diodes to meet the application voltage. Secondly, the maximum forward current should also be taken into consideration. The higher the current, the higher the power consumption. Finally, the package size and pin arrangement should be carefully checked.

In conclusion, 1N3890AR is a type of commonly used single rectifier diode which has a range of applications in different fields. The working principle and parameters of 1N3890AR should be carefully considered when selecting a proper diode. For example, the user should evaluate the reverse peak voltage, maximum current, package size and pin arrangement before making any selection. This will ensure a long lasting and reliable performance and help to prevent unexpected damages.
