Additionally, it can be mounted on the same land pattern as general and conventional TO-263 packages, allowing it to be replaced with existing circuit boards. Furthermore, “SCS2xxxNHR” for automotive equipment complies with the automotive reliability standard
AEC-Q101*4.

The production bases are ROHM Apollo Chikugo Factory (Fukuoka Prefecture) for front-end processing and ROHM Korea Corporation (South Korea) for back-end processing. Online sales have also started, and can be purchased from Chip One Stop (TM), Core Staff Online (TM), etc. ROHM will continue to develop high-voltage SBDs using SiC and contribute to energy savings and higher efficiency in automobiles and industrial equipment by providing optimal power devices that meet market needs. News release:
https://www.rohm.co.jp/news-detail?news-title=2024-11-12_news_sbd&defaultGroupId=false Background In recent years, power semiconductors are essential for OBCs and other devices installed in xEVs, which are becoming increasingly popular, and demand is increasing for SiC SBDs, which generate less heat, have high-speed switching performance, and high voltage resistance. In particular, the need for surface mount (SMD) packaged products that are small and can be mounted using a mounter is accelerating as they lead to improved application productivity. On the other hand, however, tracking tends to occur due to the application of high voltage, so devices with longer creepage distances are required. As a leading SiC company, ROHM has been working on the development of high-performance SiC SBDs that have both high voltage resistance that can support high-voltage applications and high mountability. Now, by adopting a unique shape for the package, we have secured a minimum creepage distance of 5.1 mm and developed this product with high insulation performance. Product lineup

Terminology explanation *1) Creepage distance The shortest distance between two conductors (terminals) along the surface of a device package. In semiconductor design, it is necessary to take insulation measures by ensuring creepage distance and clearance distance to prevent electric shocks, leakage, and short circuits in semiconductor products. *2) Tracking (creeping discharge) A phenomenon in which discharge occurs across the surface of an insulating package when a high voltage is applied to a terminal, which is a conductor. Discharge occurs between patterns that should not be electrically conductive, causing dielectric breakdown of the device. This phenomenon is more likely to occur as the creepage distance becomes shorter due to the miniaturization of the package. *3) Resin potting Electrical insulation is achieved by sealing the device itself and the electrode connections between the device and the circuit using resin such as epoxy. It is also effective in protecting devices,
waterproofing and dustproofing, and improving durability and weather resistance. *4) Automotive reliability standard “AEC-Q101” AEC is an abbreviation for Automotive Electronics Council, which is a
reliability standard for in-vehicle electronic components that was established by major automobile manufacturers and major electronic component manufacturers in the United States. Q101 is a standard applied to discrete semiconductor components (transistors, diodes, etc.).
