MBR0540

The MBR0540 is a Schottky barrier rectifier diode manufactured by ON Semiconductor. It is designed for applications requiring efficient rectification with low forward voltage drop and fast switching capabilities. Here’s a detailed description of its key features and specifications:

General Characteristics:

• Type: Schottky Barrier Rectifier
• Package: Typically available in a DO-41 package, which is a cylindrical glass package with two leads for easy mounting on PCBs.
• Polarity: The MBR0540 is a unidirectional diode, meaning it allows current to flow in one direction only.

Electrical Specifications:

• Reverse Voltage (VR): The MBR0540 has a maximum reverse voltage rating of 40 volts. This means it can withstand reverse bias voltages up to this level without breaking down.
• Forward Current (IF): It can handle a continuous forward current of up to 5 amperes, making it suitable for various power applications.
• Forward Voltage Drop (VF): One of the standout features of the MBR0540 is its low forward voltage drop, typically around 0.45 volts at a forward current of 5A. This low drop contributes to higher efficiency and reduced power loss in circuits.
• Reverse Recovery Time (trr): The MBR0540 exhibits a very fast reverse recovery time, which is a critical parameter for high-frequency applications. This characteristic minimizes switching losses and improves overall performance in switching power supplies and converters.

Thermal Characteristics:
