ROHM has Introduced Reference Designs for Three-Phase Inverters Featuring New SiC Power Modules

ROHM Semiconductor has recently unveiled three new reference designs—"REF68005", "REF68006", and "REF68004"—targeting three-phase inverter circuits that utilize its EcoSiC™ brand silicon carbide (SiC) molded modules, specifically in configurations such as HSDIP20, DOT-247, and TRCDRIVE pack™. This announcement was made from their offices in Santa Clara, CA, and Kyoto, Japan, on March 17, 2026.

These reference designs are now available on ROHM’s website, allowing designers to develop drive circuit boards with significantly reduced evaluation time and effort. Notably, the reference designs support output power levels reaching up to 300kW, making them applicable for various automotive and industrial initiatives. ROHM's SiC modules are already accessible for purchase via distributors like DigiKey and Farnell.

One of the challenges in using SiC power devices, while they deliver improved efficiency and reliability, is their associated increase in complexity for peripheral circuit and thermal design. Recognizing this, ROHM's reference designs are aimed at alleviating those burdens for developers. Additional resources, including simulations and thermal design support, are provided to streamline product evaluation and implementation.

For those interested in obtaining reference design boards or evaluation kits, they can reach out to ROHM’s sales representatives, although quantities are limited. Furthermore, ROHM maintains an integrated production system enhancing the quality and efficiency of its SiC devices, thus reinforcing its position as a prominent player in the SiC market. The company's commitment to innovation is evident in their extensive range of reference designs and support tools designed for market needs.

Overall, ROHM's new designs represent a significant step forward in simplifying SiC integration into high-power applications.

ROHM Semiconductor's recent launch of reference designs for three-phase inverters, featuring its new EcoSiC™ SiC power modules, marks a significant development in the semiconductor market, particularly in high-power applications. The designs REF68005, REF68006, and REF68004 present an opportunity for engineers and manufacturers to streamline their production processes, reducing time and effort spent on evaluation and thermal design.

Investors and companies operating in the semiconductor space should consider several factors stemming from this launch. First, the increasing efficiency and reliability of SiC devices over traditional silicon-based solutions is a key driver that could enhance market demand, particularly in automotive and industrial applications. ROHM's acknowledgment of the challenges in peripheral circuit design highlights their commitment to providing integrated solutions, reinforcing their position as a leader in SiC technology.

Given the projected growth of the electric vehicle and renewable energy sectors, ROHM’s strategic focus on SiC technology aligns with market trends favoring efficiency and sustainability. The fact that their SiC modules are available through popular distributors like DigiKey and Farnell further enhances accessibility, potentially expanding ROHM’s customer base.

Moreover, the inclusion of robust support resources such as simulation tools and thermal design aid strengthens ROHM's value proposition. This is an important factor for users who may be hesitant to adopt new technologies due to perceived complexity.

For investors, ROHM's innovations could lead to propelled market share and revenue growth in the long term. Companies should monitor ROHM’s performance closely as they navigate the structural changes in the semiconductor market driven by the rising adoption of SiC technology. Overall, a strategic focus on initiatives like ROHM's reference designs indicates a promising landscape for advancements in power electronics, making it an essential area to watch for potential growth opportunities.
