MURH7040R Application Field and Working Principle

The MURH7040R is an ultrafast recovery Surface Mount Rectifier diode with high current capability. It is made of an ultrafast recovery time silicon chip mounted in an DO-214AB (SMA) plastic package. The MURH7040R is mainly used in high frequency rectification, solar cell, battery charging, and other switching mode power supply (SMPS) applications.

Applications:

• High frequency rectification.
• Solar cell.
• Battery charging.
• Switched Mode Power Supplies (SMPS).

Working Principle

The MURH7040R is a single-phase rectifier diode which works on a very simple principle - when connected in an AC circuit, it will always allow current to flow in the same direction, regardless of the direction of the alternating current. This is due to the diode’s special construction, which creates a low effective resistance in one direction, but very high resistance in the other direction.

The MURH7040R also has a very fast recovery time, which means that when it is conducting current in one direction, it will quickly stop allowing current to flow in the reverse direction when the polarity of the AC voltage reverses. This helps to reduce losses in the switching mode power supply (SMPS) applications, in which the current has to be switched quickly from one direction to the other.

Conclusion

The MURH7040R is an ultrafast recovery Surface Mount Rectifier diode with high current capabilities and is mainly used in high frequency rectification, solar cell, battery charging, and switched mode power supply (SMPS) applications. Its main advantage is the ultrafast recovery time, which helps reduce losses in switching mode power supplies, and thus make them more efficient.
