Diodes Inc. Introduces New High-Efficiency Ultra-Low V(F) SBR(R) Rectifiers for Improved Efficiency in Switch Mode Power Supplies

May 9, 2007

DALLAS--(BUSINESS WIRE)--May 9, 2007--Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and supplier of high-quality application-specific standard products within the broad discrete and analog semiconductor markets, today launched a family of Ultra-Low V(F) SBR(R) power rectifiers offering industry-leading performance. Specifically targeting the PC power supply market's challenge to meet the demanding 80 PLUS(R) and Energy Star 4.0 efficiency requirements, the new family of SBR(R) power rectifiers offers industry-leading Ultra-Low V(F) and safe operating area that results in meaningful efficiency increases compared to existing industry standard parts. The Ultra-Low V(F) SBR(R) product family provides up to 85% higher reverse avalanche energy rating which allows for greater optimization and higher reliability in applications such as OR-ing and secondary rectification in AC-DC and DC-DC power supplies in end-user applications such as PC power supplies, servers, set-top boxes, telecom exchange, and medical power supplies.

"With the vast adoption of new efficiency requirements like the 80 PLUS(R) and Energy Star 4.0, the new Ultra-Low V(F) SBRs(R) are targeted to meet the growing demand for more power savings to qualify for the new efficiency standards," remarked Mark King, Senior Vice President, Sales and Marketing at Diodes Incorporated. "The Ultra-low V(F) SBR(R) devices like the SBR30U30CT have already received strong customer acceptance, including one in an 80 PLUS(R) power supply design for a major account."

The SBR30U30CT SBR(R) device is primarily targeted for secondary rectification for 3.3V and 5V output voltages for SMPS power supplies. With 85% higher reverse avalanche rating than its competitors, designers can use this inherent advantage from the SBR(R) technology to gain higher overall efficiency by using a 30V device to replace many of the traditional 45V Schottky devices that were commonly used in previously designed SMPS. This combination gives designers both performance and cost advantages in new high-efficiency power supplies.

"The SBR(R) technology, with its distinct advantages, allows us to enter into new high-volume markets, as it creates both performance- and market-driven opportunities," remarked Dr. Keh-Shew Lu, President and CEO of Diodes Incorporated. "With the release of the new Ultra-Low V(F) SBR(R) product family, we have aligned our technology development strategy with the increasing demand for more energy efficient products."

With this release, Diodes Inc. offers four new SBR(R) rectifiers for the Switch Mode Power Supply (SMPS) market. The new SBR30U30CT SBR(R) device achieves a continuous forward current rating of 30A with an ultra-low forward voltage drop (V(F)), and a high maximum junction temperature of 150 degrees C. For higher power applications, SBR40U45CT and SBR60A60CT offer lower V(F) for such end-user applications as telecom and medical SMPS where efficiency and reliability are critical to the design. In addition, Diodes Inc. is releasing a 20A/200V SBR(R) device, SBR20A200CTB, in a TO-263 package for higher output voltage rectification.
