Fairchild Launches 1200V SiC Diode

Superior switching performance targets tough energy efficiency and EMI regulations


Fairchild has released its first 1200V SiC diode, the FFSH40120ADN. The company says the diode's combination of superior switching performance, higher reliability and low electromagnetic interference (EMI) make it suitable for next-generation solar inverters, industrial motor controls and welders.

"The combination of market trends and tightening industry standards is driving the need for more energy efficient products and our new 1200V SiC diode is designed specifically to help manufacturers achieve these ever-greater efficiency requirements and with better reliability, ruggedness and cost efficiency," said Jin Zhao, VP and general manager of Fairchild's High Power Industrial division.

"We based this diode on SiC due to the material's considerable advantages over silicon, and we will add additional SiC-based semiconductors as we build a comprehensive family of SiC solutions," he added.

The FFSH40120ADN diode is claimed to have the best leakage current performance in its class, leaking far less current than its competitors at temperatures up to 175degC. Other benefits of the new diode include fast switching and no reverse recovery current, which reduces switching losses compared to silicon and results in superior energy efficiency.

The diode's ability to switch stably over a wide temperature range is another factor contributing to its performance, as is its zero recovery voltage which eliminates voltage overshoots.

 Fairchild will demonstrate the performance of the new diode at the upcoming APEC conference, March 20-24 in Long Beach, California.
