MBR7520R Application Field and Working Principle

MBR7520R belongs to the category of diodes, rectifiers and single devices. It is a 75A, 200V Schottky Barrier Rectifier, in a surface mount package. It has low losses, high temperature-stable operation, low forward voltage drop, and high surge current capability.

Application Field

MBR7520R is applicable to many different types of power supply and voltage regulator circuits, including switched mode power supplies (SMPS), uninterruptible power supplies (UPS), motor drives, LED lighting power supplies and many other types. It is suitable for medium to high-power applications and is usually used in automated circuit protection circuits.

Working Principle

The MBR7520R is a Schottky barrier diode employing a metal-semiconductor junction as its rectifying junction. The metal is usually a metal with a wide band gap, such as platinum, gold, nickel, or tantalum. Schottky barrier diodes offer lower forward voltage drops, relatively higher turn-on current and higher junction capacitance than the more common P-N junction diodes. This makes them attractive for high-efficiency applications such as switching power supplies and regular rectifiers. The advantages of the MBR7520R also include low recovery time, low forward voltage drop, wide I/O isolation, and high maximum reverse current.

In operation, when a current flows, the MBR7520R\'s metal-semiconductor junction behaves like a diode, allowing electrical current to flow in one direction, while blocking current flowing in the opposite direction. The metal-semiconductor junction prevents electrical charge to build up in the device, eliminating reverse current leakage at higher voltages.

Conclusion

The MBR7520R is a useful device for a variety of power supply, voltage regulator and circuit protection applications. Its low losses, high temperature-stable operation, low forward voltage drop, and high surge current capability make it uniquely suitable for many types of applications. With the proper use and selection of components, the MBR7520R can be reliably used to ensure reliability and efficiency in many types of circuits.
