Share this on: Bosch and Fuji Electric create dual-source opportunity for power modules More flexibility and reliability for automotive manufacturers The electrification of drive trains continues to drive demand for innovative power modules that combine high power density, reliability, and smooth integration into inverters. At the same time, automotive manufacturers want to ensure supply chain security by sourcing these modules from multiple suppliers. This is where Bosch and Fuji Electric come into play: By creating greater mechanical exchangeability of their corresponding silicon carbide (SiC) power modules, the two companies meet the need for highly specialized designs while maintaining the flexibility of multi-sourcing. A shared design for maximum customer benefit The main dimensions of both power modules have been aligned, allowing manufacturers to integrate either module into their inverter housing or technical set-up with significantly reduced mechanical effort. This minimizes the required adaptations on behalf of customers when using both module options in their system. And the next steps are already underway: Bosch and Fuji recently signed a memorandum of understanding to continue the successful process on further details of the next release of PM6 power module geometry based on customer feedback. Furthermore, the two companies intend to offer technical documentation supporting the mechanical application of the power modules, such as cooler soldering and contact interface welding. Securing flexibility in a demanding market This combination of aligned mechanical dimensions and harmonized application support allows manufacturers to maintain seamless system integration and production consistency, even when sourcing from both companies simultaneously. Moreover, this flexibility significantly strengthens supply chain resilience. “A multi-supplier approach lays the foundation for the customer’s sustainable growth and long-term technological independence”, Mr. Tadashi Miyasaka, General Manager Automotive Division, Semiconductors Business Group, Fuji Electric Co., Ltd. summarizes. PM6: state-of-the-art SiC power modules on cooler Open module of PM6.0 platform The Bosch PM6 power modules combine advanced SiC technology with a smart 3D design to deliver strong and stable performance in electric drive systems. Their compact layout minimizes electrical resistance and energy losses while preventing unwanted oscillations between connected chips. Thanks to the efficient cooling structure with copper layers that distribute heat evenly, the modules achieve high power density and maintain reliability even under demanding thermal conditions. Their design also balances thermal expansion between materials, ensuring long-term mechanical stability and durability. The PM6 power modules can be configured flexibly – from four to twelve chips of different sizes – to cover a wide range of power requirements. PM6.2: supply chain security through exchangeability The PM6.2 builds on the core architectural strengths of the PM6 portfolio, while introducing various enhancements such as optimized pinning and more temperature sensing options. Moreover, it was designed with a strong focus on ensuring supply chain security for customers. “In today’s fast-paced automotive production, consistency of technical parameters on component level is important. To improve time to market and decrease engineering efforts, differences in package dimensions, connection layouts, or cooling interfaces must be kept as small as possible,” says Ralf Bornefeld, SVP, General Manager of the Business Unit Power Semiconductors and Modules, Robert Bosch GmbH. This is why Bosch and Fuji have agreed to offer an additional option within the respective portfolios that will share a similar package outline with aligned key mechanical dimensions.
