Cree Releases Packaged 1700V SiC Schottky Diodes for Solar, Motor Drive and Traction Applications
Cree, Inc. has introduced a series of packaged diodes that the company says deliver the industry’s highest blocking voltage available in SiC Schottky technology. Cree’s 1700V Z-Rec® Schottky diodes virtually eliminate the reverse recovery losses suffered in silicon PiN diode alternatives, enabling ultra-efficient, smaller and lighter systems – all with improved reliability. These newly released packaged products extend the performance improvements and system cost savings enabled by Z-Rec technology at 1700V to lower-power applications designed with discrete components.

"Cree’s 1700V silicon carbide Schottky diodes are well suited for high-efficiency power electronics systems," explained Cengiz Balkas, Cree vice president and general manager, Power and RF. "They provide all the proven benefits of Cree’s Z-Rec SiC Schottky diodes – zero reverse recovery losses, temperature-independent switching and higher frequency operation."
While the 1700V bare die have been available for customers who design their own custom power modules, the new TO-247-2 packages allow customers to take advantage of SiC for lower-power 1700V designs, enable more design flexibility in choosing current levels, and support a faster time to market.

"The availability of 1700V SiC Schottky diodes provides a number of advantages for design engineers in high-voltage power applications," added Balkas. "Silicon carbide diodes enable maximum power efficiency and better EMI performance. The switching loss improvement allows for increased system frequencies that can reduce the size of magnetic and capacitive components. Significant reductions in system size, weight and cost can be achieved. Moreover, the availability of 1700V SiC diodes can eliminate the need for stacking multiple lower voltage silicon diodes, thereby cutting component count, improving thermal performance and increasing reliability."
Designated the C3Dxx170H Series, the new Cree SiC Schottky diodes are rated for 10A/1700V and 25A/1700V and are available in an industry standard TO-247-2 package. Operating junction temperature is rated for -55 to +175°C.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
