Introduction

The MBR7520 is a single, surface mount, glass passivated rectifier bridge. This bridge, or a pair of them, is typically used in many applications, for a variety of tasks such as rectifying AC current and controlling current flow in a circuit. The MBR7520 is able to pass relatively large amounts of current for its small size, making it a popular choice for many applications.

Application Field

The MBR7520 is used in many different types of electronics and electrical systems. These include power supplies, voltage regulators, automotive systems, and many other types of applications that require current control and/or AC/DC conversion. Some of the most common uses of the MBR7520 are as a reverse polarity protection device, and as a voltage stabilizer. In these applications, the MBR7520 serves to regulate the current an system can utilize, preventing overload and damage to components.

In automotive systems, the MBR7520 can be used to power up the system quickly, prevent the electrical system from overloading, and provide the vehicle with both AC and DC power. Additionally, the MBR7520 can be used in solar PV systems, mobility aids, and even home use applications such as power adapters.

Working Principle

The MBR7520 works by utilizing the natural tendency of electrical current to flow from high-voltage to low-voltage. It then uses this to switch the direction of the current from one to another, allowing for either AC or DC power. This is done by the four diodes within the MBR7520 which are connected in the form of a bridge, hence the term rectifier bridge. The diodes have an anode and cathode, allowing current to only flow in one direction, making them ideal for this type of application.

In operation, current flows through the bridge in either direction, depending on the polarity of the voltage. When current is flowing in a single direction, it can be used as either AC or DC power. When the voltage has opposite polarities, the MBR7520 acts as a switch, switching the current from one polarity to another. This allows for efficient current control and current switchover, making it a popular choice for many applications.

Conclusion

The MBR7520 is a versatile rectifier bridge which can be used in a variety of applications. It is small and highly efficient, and is able to provide reliable current control and switchover which is invaluable to many electronics and electrical projects. It is durably constructed and its use can be seen in a variety of industries, from automotive systems to solar panel installations.
