Diodes - Rectifiers - Single

The MBR735HE3/45 is one of many diodes in the rectifier category. Diodes are current-regulating components used in a variety of applications. Rectifier diodes are used to reverse the current flow in rectifier circuits, power supplies, and power system control.

Application Field of MBR735HE3/45

The MBR735HE3/45 is a single-phase bridge rectifier rated for use in applications that need up to 45-A dc current. These applications include but are not limited to AC/DC conversion, battery charging, alternating current line regulation, or DC/DC conversion.

In telecommunication systems, MBR735HE3/45 diodes may be used in circuits that provide a degree of transient protection to the circuits they are connected to. They may also be used in rectifier circuits which are used to convert AC input signals to DC signals.

Power supply systems, in particular, may also make use of MBR735HE3/45 diodes as power supplies can utilize rectifier circuits to provide suitable DC power for operation. In addition, the MBR735HE3/45 diode may be used in power system control applications to divert stored energy in case of a power outage.

Working Principle of the MBR735HE3/45

The MBR735HE3/45 is an integrated bridge rectifier with an individual breakdown voltage rating of 700 volts and a blocking voltage of 800 volts. This type of bridge rectifier is also known as a full-wave bridge rectifier and works by dividing the input voltage into two equal parts, applying the same output voltage to both parts, but in opposite directions.

It is this action of the bridge rectifier that enables the conversion of the alternating current voltage or AC voltage into direct current voltage or DC voltage. The MBR735HE3/45 can handle up to 45 A of current and has a reverse recovery time of 25 nanoseconds.

A bridge rectifier can be configured using four diodes in a bridge configuration. It has polarity reversal that ensures that the positive and negative cycles of the input alternating current supply are converted into full-wave rectification. The voltage output of the bridge rectifier is then made available for its intended application.

The bridge rectifier is composed of four diodes arranged in a diamond-shaped configuration. The current input is applied across two points and the voltage output is produced across the other two points. This arrangement of diodes allows for current to flow in both directions.

The working principle of the MBR735HE3/45 is a combination of the two previous principles. It is composed of four individual diodes in a bridge rectifier configuration and provides the current rectification to an alternating current supply. It also allows for the restoration of the original supply voltage and current level, ensuring the availability of suitable DC power.

The working principle of the MBR735HE3/45 is the same regardless of what supply is used and it is an integral part of any application that may require current or voltage rectification.

Conclusion

The MBR735HE3/45 is a rectifier diode used for current and voltage rectification and can be found in a variety of applications such as power supplies, telecommunication systems, and power system control. It is composed of four individual diodes in a bridge rectifier configuration and is rated at up to 45-A of current.

The device works by dividing the input current in two, applying the same voltage to both and in opposite directions. This enables the MBR735HE3/45 to provide full-wave rectification, allowing for the restoration of the original input voltage and current level.
