Ixys Announces Ultra Fast 1200V SiC Schottky Diodes

News
Dual diodes in MiniBLOC package enable higher power applications

Ixys has announced two new ultra fast dual 1200V SiC Schottky Diodes. The fully isolated DCG45X1200NA and the DCG130X1200NA both offer two SiC Schottky diodes with an average forward current of 2 x 22A and 2 x 65A, respectively at 80degC case temperature and essentially zero forward and reverse recovery.

"With these new products we are expanding our fast diode portfolio and enable applications with higher power in switching and control for inverters, UPSs and rapid charger solutions," states Elmar Wisotzki, director of technology for Ixys Germany. "Our SiC schottky portfolios give our customers more flexibility in choosing the right product for their application to improve efficiency at best performance-over-cost ratio. The SOT-227 package is a good match with our standard Power MOSFETs and IGBTs, enabling a low profile and high power density design."

According to Ixys, the positive temperature coefficient of the forward voltage drop makes it easy to parallel devices for higher output power. The MiniBLOC package of the new products uses an advanced isolation structure with an optimised low thermal resistance. Lower dynamic losses and reduced thermal impedance allow for reduction of system size because of higher power density and switching frequency. Added benefits are an increase in reliability because of a lower die temperature swing in cycling power demand.

The diodes inside the package are electrically isolated from each other, allowing the designer to connect them either in parallel and build common cathode or phase leg configurations.

Typical applications are high efficient DC-DC converters, power inverters, uninterruptible power supply (UPS) systems, high performance power supplies, welding equipment and rapid-charger solutions.
