Cree Releases Zero Recovery Rectifier For Computer Power Supplies

Cree, Inc. announced the release of a new 8A, Zero Recovery® rectifier that is said to significantly increase power-supply efficiency in computer servers. The new CSD08060 Schottky diode is said to save energy while boosting power-supply performance.

The CSD08060 8A SiC rectifier also expands Cree’s Zero Recovery product line, which includes 600V diodes with 1, 2, 4, 6, 10, and 20A ratings. The company claims that, compared with traditional silicon-based diodes, its SiC-based rectifiers can: simplify PFC Boost design; eliminate the need for snubbers; reduce power losses, leading to cooler operating temperatures; produce significantly less electromagnetic interference (EMI); offer faster switching speeds without reverse recovery currents; enable streamlined circuit design resulting in smaller board size and component counts; and allow higher power density designs for compact power supplies for high performance applications.

"Cree is taking a leadership role in solving a significant global energy problem – the increasing power demands from large server farms. Our new Schottky diode can significantly improve the efficiency of the power factor correction circuits used in switch mode power supplies," said John Palmour, Cree Executive Vice President of Advanced Devices. "By replacing silicon-based rectifiers with the new 8A SiC Zero Recovery rectifier, power supply manufacturers can cut power losses by at least 10% in a typical 1kW server power supply."

The Cree CSD08060 is available in production quantities.
