DL4005-13 Application Field and Working Principle

The DL4005-13 is a single-phase, bridge rectifier from Diodes Incorporated. This bridge rectifier is mainly used for power supplies and adapters, AC/DC power converters, power inverters, DC-DC converters, battery chargers, and lamp ballasts. This device is available in a Through-Hole (TO-220) SMD (SMD-220) package, making it easy to use with any existing designs.The DL4005-13 bridge rectifier is designed to withstand high surge current and has peak repetitive reverse voltage of 400V and continuous reverse voltage of 400V. The peak uncontrolled surge current is 3.2A. The average rectified output current at 55°C of the device is 5A and junction temperature of the device is maximum 175°C. This device has a low forward voltage drop of 1.1V (typical) and low reverse leakage current of 100µA (maximum) at reverse voltage of 300V.In terms of its operation, the DL4005-13 bridge rectifier provides one-way current conduction. It is composed of 4 diodes arranged in a bridge formation making it suitable for easy full-wave rectifying. The device is capable of converting alternating current (AC) to direct current (DC).When the AC voltage is applied across the device terminals, the upper diodes D1 and D3 will conduct. D2 and D4 will not conduct. In the following cycle, the lower diodes D2 and D4 will conduct and D1 and D3 will not conduct.This process is repeated ultimately resulting in full-wave rectification. The output DC voltage is quite close to the peak value of the AC voltage. Therefore, the bridge rectifier is capable of providing an efficient and steady DC output.

Conclusion

The DL4005-13 single-phase bridge rectifier from Diodes Incorporated is an ideal choice for applications such as power supplies, adapters, AC/DC power converters, power inverters, DC-DC converters, battery chargers, and lamp ballasts. The device is easy to use with its Through-Hole and SMD packages and can withstand high surge current. Furthermore, it provides full-wave rectification with its four diode bridge formation, resulting in a DC output close to the peak value of the AC voltage.
