Zero Recovery Rectifier Boosts Efficiency in Computer Power Supplies
DURHAM, NC, OCTOBER 11, 2007 - Cree, Inc. (Nasdaq: CREE), a market leader in silicon carbide (SiC) power semiconductors, today announced release of a new 8-amp, Zero Recovery® rectifier that significantly increases power-supply efficiency in computer servers. The new CSD08060 Schottky diode extends Cree's leadership in rectifiers that save energy while boosting power-supply performance.
The CSD08060 8-amp SiC rectifier also expands Cree's Zero Recovery product line, which includes 600-V diodes with 1A, 2A, 4A, 6A, 10A, and 20A ratings. Compared with traditional silicon-based diodes, Cree SiC-based rectifiers can:
o Simplify PFC Boost design
o Eliminate the need for snubbers
o Reduce power losses, leading to cooler operating temperatures
o Produce significantly less electromagnetic interference (EMI)
o Offer faster switching speeds without reverse recovery currents
o Enable streamlined circuit design resulting in smaller board size and component counts
o 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 8-amp SiC Zero Recovery rectifier, power supply manufacturers can cut power losses by at least 10 percent in a typical 1kW server power supply."
The Cree CSD08060 is available in production quantities. Additional information about Cree Silicon Carbide Zero Recovery rectifiers may be obtained by calling Cree at 919-287-7836 or by visiting www.cree.com.
