DSS2X81-0045B Application Field and Working Principle

DSS2X81-0045B, belonging to the diode-rectifiers-arrays category, is commonly used in telecom, high-end home entertainment electronics, automotive voltage regulator modules and battery charging systems. It is made up of two 30V Schottky rectifiers encapsulated in tiny, space-saving surface-mount packages.

This device is designed to provide low voltage drop and low forward conduction losses. It also helps reduce the system cost and size. Its package contains two Schottky rectifiers with a dedicated terminal for each device. It helps reduce the amount of space consumed by conventional packages and allows for better power handling.

Working Principle

DSS2X81-0045B is designed to function as a switching Power Rectifier with a maximum forward current rating of 45A. It is typically used in applications where low voltage drops and low conduction losses are required. It also helps reduce noise emission and frequency interference.

In its normal operation, the device is off and no current flows through it. When the anode is positive with respect to the cathode, the Schottky barrier between them is no longer able to stop current. The current across the two terminals (and the load) is thus a combination of the anode current, the leakage current and the reverse recovery current.

The rectifier\'s forward voltage protects the load from overcurrents, while its reverse voltage clamps prevent excessive voltages from entering the load. The current level and temperature of the device is monitored, and the threshold level and temperature is variable depending on the device\'s needs.

Advantages of DSS2X81-0045B

The DSS2X81-0045B has several advantages over conventional rectifiers. It provides a low forward voltage drop, allowing for better power handling. Its ultra-small package allows for improved space utilization and an increased number of termination sites for connection to the load. Its low reverse leakage current helps reduce power loss and increases the system\'s efficiency. Its temperature compensation feature helps reduce thermal stress, making it more reliable and longer lasting. Finally, its tin/lead plating helps improve its soldering performance.

Conclusion

The DSS2X81-0045B is an efficient and reliable diode-rectifier-array that provides significant benefits to applications such as telecom, high-end home entertainment electronics, and automotive voltage regulator modules and battery charging systems. With its low forward voltage drop, ultra-small package, low reverse leakage current, temperature compensation, and tin/lead plating, the DSS2X81-0045B is an ideal rectifier for modern applications.
