Diodes - Rectifiers - Single

The DUR60120W is a single-phase, full-wave bridge rectifier with a maximum continuous forward current of 60A and a peak repetitive surge current of 200A. It is made of four ultra-fast recovery diodes and uses its Schottky diode technology for improved performance.It has a forward voltage drop of 0.77V per diode at a current of 60A making it a cost effective solution for low-power applications such as computers and power supplies.

Application Field

The DUR60120W is typically used in industrial and power applications where reliable power delivery is a priority. It can be used as a part of an AC-to-DC power supply, either as the input rectifier or the intermediate rectifier prior to the DC output voltage regulation stage. The low forward voltage drop of 0.77V per diode at a current of 60A provides low-power applications with reliable current delivery that can reduce power consumed. The ultra-fast diode used gives good performance over wide range of temperature and humidity. The short-circuit protection and reverse-polarity protection makes it suitable for a wide range of applications.The DUR60120W can also be used in traction systems and other industrial applications where consistent power delivery is necessary. In applications such as these, the breakdown of the diode may occur due to over current and over heating. The integrated temperature sensing protect circuits prevent this. The built-in thermal shut down also activates to prevent damage to the rectifier from over-temperature occurrences.

Working Principle

The basic principle of a full-wave rectifier is to convert AC power to DC by passing the AC waveform through a diode bridge. The DUR60120W uses four ultra-fast recovery diodes arranged in a bridge structure, connecting the input AC to the load. During the positive cycle of the AC wave, the upper diodes (D1 and D3) of the bridge are forward-biased, allowing the current to flow from the AC source to the load. Similarly, in the negative half of the AC cycle, the lower diodes (D2 and D4) are forward-biased while the upper diodes are reverse-biased. This allows the current to flow from the AC source to the load. The Schottky diode technology used in the DUR60120W helps to reduce power consumption, improve response times and eliminate reverse recovery time. A Schottky diode has a more attractive price to performance ratio as compared to other diodes, which makes it ideal for power applications where efficiency and cost effectiveness are important.The DUR60120W is packaged in an IP67 compliant, plastic enclosure for improved protection, making it suitable for outdoor applications. The plastic shell protects the diodes from dust and water, and the high temperature enclosure prevents it from overheating. This makes it reliable and suitable for a range of applications.

Conclusion

The DUR60120W single-phase, full wave bridge rectifier is a suitable choice for low-power applications such as computers, power supplies, traction systems, and other industrial applications, where consistent power delivery and protection from over-current and over-heating is required. The Schottky diode technology used helps to reduce power consumption and improve response times, making it cost effective solution for those applications. The built-in thermal shut down and IP67 compliant plastic enclosure also ensures that the rectifier is reliable and suitable for a wide range of applications.
