Diodes - Rectifiers - Single

The FR85J02 is a single diode rectifier designed to be used in various power management applications. Its features, such as its low forward voltage drop, low reverse leakage current, and very small package size, make it an ideal choice for many power supply designs. This article will discuss the application field and working principle of the FR85J02.

Application Field

The FR85J02 is a single diode rectifier designed for power management applications. It can be used in many different designs, including off-line power applications, AC/DC converters, battery chargers, and LED lights.

The FR85J02 is well-suited for off-line power applications as it has a low forward voltage drop of only 0.9V, a low reverse leakage current of 1.0mA, and a very small package size. It is also capable of handling high surge currents up to 17A. With these features, it is able to efficiently convert AC input into DC output.

The FR85J02 is also suitable for AC/DC converters, as it is able to efficiently handle large AC input signals and provide a stabilized DC output. It is capable of handling peak power up to 36W, so it is the perfect choice for a wide range of AC/DC converters.

In addition, the FR85J02 is well suited for battery chargers. It can provide efficient and reliable charging, even when the battery is being rapidly drained. The low forward voltage drop and low reverse leakage current make it an ideal choice for battery chargers. It is also capable of handling peak charging current up to 7A, so it is able to efficiently charge large batteries.

Finally, the FR85J02 can also be used in LED lights. Its 0.9V forward voltage drop and very small package size makes it an ideal choice for LED lights, as it is capable of providing efficient and reliable lighting. It is also easy to install, making it a great choice for any LED lighting project.

Working Principle

The FR85J02 is a single diode rectifier. It works by converting AC input signals into DC output signals. When the AC input signal is applied to the diode, it will pass through the diode and be rectified. This rectified DC signal will then be output from the diode. The diode’s internal resistance helps to regulate the output voltage, so that it is within the desired range.

The FR85J02 also has a low forward voltage drop of only 0.9V, which helps to reduce power losses. The low reverse leakage current of 1.0mA also helps to conserve power. The diode’s package size is also very small, making it easy to install and saving space in the design.

In summary, the FR85J02 is a single diode rectifier designed for power management applications. It is capable of handling peak power up to 36W, making it an ideal choice for both off-line power applications and AC/DC converters. In addition, it has a low forward voltage drop and a low reverse leakage current, which makes it well-suited for battery chargers and LED lights. Finally, its working principle is to convert AC input signals into DC output signals, using the diode’s internal resistance to regulate voltage.
