In recent years, a growing number of automakers have been offering electric vehicles in response to increasing environmental awareness and rising fuel costs. However, while electric vehicles are becoming more widespread, their relatively short range continues to pose challenges. To improve range, batteries are increasingly increasing their capacity while offering shorter charging times. This, in turn, demands high power and efficiency from onboard chargers, such as 11kW and 22kW, leading to the increasingly common use of SiC MOSFETs. Furthermore, high-voltage (800V) batteries require power devices with low losses and higher withstand voltages.
To meet these needs, ROHM has added 10 new models to its AEC-Q101 rated MOSFET range
, which utilizes a Trench structure. The result is the industry's largest portfolio, available in 650V and 1200V variants. Looking ahead, ROHM will continue striving to further improve quality and strengthen its product range to increase device performance, reduce power consumption, and achieve greater miniaturization.
In December 2010, ROHM became the first company in the world to successfully implement mass production of SiC MOSFETs and continues to lead the industry in the development and mass production of SiC power devices. Particularly in the automotive market, where demand is increasing, ROHM quickly established automotive-grade quality and began supplying SiC Schottky barrier diodes for on-board chargers in 2012 and SiC MOSFETs for DC/DC converters and on-board chargers starting in 2017.
Guided by the corporate objective of "Quality First," established since its founding, ROHM utilizes a vertically integrated production system within the group that instills superior quality in every process, from development to final testing, while providing reliable traceability and an optimized supply chain. For SiC power devices, an integrated production system is also used, covering everything from wafer fabrication to packaging, to eliminate "black boxes" during the manufacturing process, thus ensuring greater reliability and quality.
