ROHM Unlocks SiC Power Modules with New Online Sales Strategy

SANTA CLARA, CA – March 12, 2026 – In a strategic move set to ripple through the power electronics industry, ROHM Semiconductor has made its latest high-performance Silicon Carbide (SiC) power modules available for online purchase. The launch democratizes access to technology previously reserved for large-scale industrial clients, empowering a wider range of engineers and innovators to design the next generation of energy-efficient systems.

Effective immediately, three new series of SiC molded modules—the TRCDRIVE pack™, HSDIP20, and DOT-247—can be purchased directly from major online distributors like DigiKey and Farnell. This shift from traditional procurement channels to e-commerce marks a significant step in accelerating the adoption of SiC, a critical material for advancing electric vehicles (EVs), renewable energy infrastructure, and high-efficiency industrial equipment.

The Democratization of Power Electronics

Historically, acquiring cutting-edge power modules involved navigating complex supply chains, meeting high minimum order quantities, and establishing direct relationships with manufacturers. ROHM's decision to list these advanced components online dismantles these barriers, creating new opportunities for a diverse set of customers.

Startups, small and medium-sized enterprises (SMEs), and university research labs can now procure single units or small batches for prototyping, testing, and low-volume production. This streamlined accessibility is expected to foster innovation by enabling more designers to experiment with SiC technology, which offers superior efficiency, higher power density, and better thermal performance compared to traditional silicon.

By placing its most advanced products on globally accessible platforms, ROHM is not just selling components; it is seeding the market for future growth. Engineers working on novel EV charging solutions, compact solar inverters, or next-generation server power supplies can now integrate industry-leading technology into their designs faster and with less administrative overhead, potentially shortening development cycles from months to weeks.

Powering the Next Wave of Electrification

The new modules are engineered to address some of the most demanding challenges in modern electronics. Each product family targets key growth sectors and leverages ROHM’s 4th Generation SiC MOSFETs for breakthrough performance.

• TRCDRIVE pack™: This 2-in-1 module is a game-changer for the automotive sector, specifically designed for xEV traction inverters up to 300kW. ROHM claims it delivers an industry-leading power density 1.5 times higher than competing SiC modules. This allows for significant miniaturization of the inverter, a critical component in EVs, leading to lighter, more spacious, and more efficient vehicles. Its unique terminal layout also simplifies assembly, reducing installation time on the manufacturing line.

• HSDIP20: Offered in versatile 4-in-1 and 6-in-1 configurations, the HSDIP20 series is a highly integrated solution for applications like EV onboard chargers (OBCs), DC-DC converters, and EV charging stations. By consolidating multiple power stages into a single compact package, these modules reduce design complexity and component count, enabling manufacturers to build smaller and more reliable power conversion systems.

• DOT-247: Aimed at industrial applications such as PV inverters, uninterruptible power supplies (UPS), and AI data centers, the DOT-247 module provides high power density in a familiar package. It retains the versatility of the widely used TO-247 footprint while supporting flexible half-bridge and common-source circuit topologies. This allows engineers to upgrade existing silicon-based designs to SiC with minimal redesign, reducing both board space and development effort.

Navigating a High-Stakes Market

ROHM's strategic pivot comes at a time of explosive growth in the SiC market. Industry analysts project the SiC power semiconductor market to soar from just over $3 billion in 2026 to more than $10 billion by 2031, with some forecasts showing a compound annual growth rate (CAGR) of nearly 30%. The automotive sector is the primary engine of this growth, accounting for over 60% of demand as the industry shifts towards 800V architectures that rely on SiC for efficiency and fast-charging capabilities.

This lucrative market is fiercely competitive. ROHM, which held approximately 8% of the market share in 2022, is vying against established giants like STMicroelectronics, Infineon Technologies, Onsemi, and Wolfspeed. These competitors command significant market share and have their own robust SiC product portfolios and extensive supply agreements with major automotive and industrial players.

In this high-stakes environment, ROHM’s strategy appears twofold. First, it is leveraging its technological prowess under the EcoSiC™ brand, which represents a vertically integrated production system—from raw SiC wafer fabrication to final module packaging. This control over the supply chain is a key advantage in a market prone to disruptions. Second, the online distribution strategy is a clever maneuver to capture the long tail of the market, building brand loyalty and a broad customer base that could scale into significant future business.

Driven by Global Efficiency Mandates

The entire SiC boom is underpinned by a powerful global current: the urgent need for energy conservation. As concerns over climate change and power grid stability intensify, governments and regulatory bodies worldwide are implementing stricter efficiency standards. Initiatives like the EU Green Deal and EPA standards in the United States are accelerating the transition away from less efficient silicon-based power electronics.

SiC technology is a direct answer to these mandates. In EVs, it extends driving range and enables faster charging. In renewable energy, it boosts the efficiency of solar inverters, maximizing the power harvested from every panel. In data centers, it reduces the enormous energy consumption required for cooling and operation. Even industrial motor drives, when equipped with SiC, have demonstrated significant energy savings, influencing new building codes and standards.

By launching these advanced, application-specific modules and making them widely available, ROHM is not only responding to market demand but actively enabling the industries at the forefront of electrification and sustainability. This move positions the company as a key supplier for the green energy transition, providing the fundamental building blocks required to build a more efficient and electrified world.
