ROHM's SiC SBD was successfully used in the data center power module of Murata Power Solutions, a subsidiary of the Murata Manufacturing Group

The third-generation SiC Schottky diode (hereinafter referred to as "SBD") developed by ROHM (headquartered in Kyoto, Japan), a world-renowned semiconductor manufacturer, has been successfully used in Murata Power Solutions' products . Murata Power Solutions is a company under the Murata Manufacturing Group, a well-known Japanese manufacturer in the fields of electronic components, batteries, and power supplies. ROHM's high-speed switching SiC SBD product "SCS308AH" was successfully used in Murata Power Solutions' data center power module "D1U series" and contributed to the performance improvement and size reduction of this series of products.

In recent years, with the development of the IoT field represented by technologies such as AI (artificial intelligence) and AR (augmented reality), global data communication volume is growing. Especially for data centers responsible for communication management, the miniaturization and efficiency improvement of their servers have become technical problems that plague various manufacturers. Against this background, SiC power devices are highly anticipated as they contribute to the miniaturization and efficiency of the power supply section.

Dr. Longcheng Tan, Senior Electrical Engineer and project leader, Murata Power Solutions said: "By using SiC power devices, power products with higher efficiency and higher power density can be developed. At the same time, SiC power devices can also increase the switching frequency, This can reduce the size of passive components and heat sinks. The Murata Manufacturing Group has a department specifically responsible for evaluating SiC device manufacturers and their products. The reason why we chose ROHM this time is because of the high reliability of ROHM products. What’s more, ROHM’s service support is very fast and samples can be provided right from the trial production stage. In addition, ROHM’s SiC MOSFETs are also used in the three-phase inverter we are developing, and the related products can meet our performance requirements.”

Jay Barrus, President, ROHM Semiconductor USA, LLC said: "I am truly pleased to be able to support Murata Power Solutions, a leader in industrial equipment such as power systems. ROHM is a leader in SiC power components and is one of the best in the industry. ROHM is the first to provide power solutions that combine advanced component technology and driver IC products, and has achieved impressive results. In the future, ROHM will continue to work together with Murata Power Solutions to go as deep as possible through the industrial and data infrastructure fields. Explore the potential of SiC technology to further improve the energy efficiency of power systems.”

＜About Murata Power Solutions’ data center power modules＞

Murata Power Solutions has added the high-efficiency power factor corrected front-end power supply modules "D1U54P-W-2000-12-HB3C" and "D1U54P-W-1200-12-HC4PC" to its AC-DC power supply "1U front-end" series lineup. " and other products can realize parallel operation of multiple power modules. In addition, the "1U front-end" series also supports hot-swapping and has abnormal detection and protection functions such as overheating, overcurrent, and overvoltage. This series of products can not only provide highly reliable and efficient power supplies for 12V power systems such as servers, workstations, and storage systems, but also have a thin size (1U), which helps reduce the installation area of ​​the system.

＜About ROHM’s SiC power devices＞

Since ROHM started mass production of SiC MOSFETs globally in 2010, as a leader in the field of SiC power components, it has been promoting the technological development of advanced products. The new 3rd generation SiC SBD products used by Murata Power Solutions feature small total charge (QC), low loss and high switching speed. Moreover, compared with the second generation SBD, its surge current resistance is better and its VF value is lower.
