FR85DR02 is a diode rectifier with a single configuration. It is a bridge rectifier, meaning it has two polarities of voltage in its design. This type of diode is used in a wide range of applications, such as power conversion, rectification, current and voltage regulation, liners and switch-mode power supply circuits and more.

The main purpose of a rectifier is to convert alternating current (AC) power to direct current (DC) power. This is achieved by using the unique switching characteristics of diodes to produce either a full-wave or half-wave rectification depending on the type of rectifier used. Rectifiers are also used in filtering applications to reduce the amount of AC ripple in a power circuit.

The FR85DR02 rectifier is a single, single-phase full-wave bridge rectifier consisting of four power diodes. It is an encapsulated structure and has a package size of 6.9x4.9x4.5mm. It has a maximum forward voltage of 50V and can handle up to 3A through its terminals. It also has a built-in surge protection element that limits the peak surge fault current.

In a full-wave bridge rectifier, the four individual diodes are connected in a bridge-like configuration; two diodes in series to form two arms of the bridge and two more series-connected diodes to form the other two arms. This ensures that the AC voltage is converted to DC voltage while the polarity of the voltage is preserved. The two diode arms form a single straight line, which is called a full-wave rectification. This type of rectifier eliminates the need for a dedicated center tap transformer and allows for the use of a simpler, less expensive transformer design. This makes it ideal for applications such as low power AC/DC power supplies.

The FR85DR02 rectifier operates at a frequency over a broad range and can work in any voltage environment that is compatible with the rectifier’s ratings. The power diodes used in this bridge rectifier have a high forward voltage drop which allows for good switching speeds and low standby losses. This makes it suitable for pulse width modulation applications, such as PWM power supplies and solar battery chargers.

The FR85DR02 is an encapsulated rectifier, meaning it is sealed and protected from environmental elements like dust and moisture, providing robust performance and a long service life. This makes it ideal for use in harsh environments and in applications where a exposed connection would be more susceptible to damage.

In summary, the FR85DR02 is a single-phase, full-wave bridge rectifier diode with a maximum forward voltage rating of 50V and a current handling of up to 3A. It is a packaged design to protect it from environmental damage and its high forward voltage drop allows for good switching speeds. Its wide operating frequency allows it to be used in a range of switching frequency applications and its high surge fault current limit makes it suitable for high peak power applications such as PWM and solar power charging systems.
