Innovative DOT-247: Revolutionizing SiC Module Design
Introducing the Groundbreaking DOT-247 Module
ROHM Semiconductor has unveiled an exciting development in the realm of silicon carbide (SiC) technology—the DOT-247 module. This innovative 2-in-1 molded module is designed specifically for industrial applications, including photovoltaic (PV) inverters, uninterruptible power supplies (UPS), and semiconductor relays. The DOT-247 seamlessly blends the reliability of the widely used TO-247 package with enhanced design flexibility and improved power density, representing a significant advancement for industries reliant on cutting-edge electrical solutions.
Key Features of the DOT-247 Module
One of the standout characteristics of the DOT-247 is its unique dual TO-247 structure. This allows for the incorporation of larger chips that were previously challenging to integrate. With an innovative internal design that achieves lower on-resistance, this new module is optimized to decrease thermal resistance by around 15% while also minimizing inductance by nearly 50% when compared to traditional TO-247 solutions. This combination leads to a remarkable 2.3-fold increase in power density within half-bridge configurations, permitting equivalent power conversion capabilities to be achieved in nearly half the volume.
Flexibility in Application Design
The DOT-247 is offered in two distinct topologies: half-bridge and common-source. This is especially crucial as the demand for sophisticated multi-level circuits continues to grow. While two-level inverters remain the standard in PV systems, there is an increasing need for advanced configurations like three-level NPC, three-level T-NPC, and five-level ANPC to handle higher voltage requirements. Standard SiC packages often struggle with the integration of both half-bridge and common-source setups due to the inherent complexities. However, with ROHM's standardized 2-in-1 modules, developers gain increased flexibility when designing NPC circuits and DC-DC converters, effectively reducing component counts and optimizing board space for more compact circuitry.
Evaluation Support and Availability
To further ease the implementation process, ROHM promises to provide evaluation boards aimed at assisting designers during their development phases. Those interested in exploring the advantages of the DOT-247 can connect with sales representatives or visit the dedicated contact page on ROHM's website for more detailed information.
Application Examples
The DOT-247 is not just versatile; it excels across a range of high-demand applications. These include PV inverters, semiconductor relays, UPS (uninterruptible power supplies), electric power take-offs (ePTO), boost converters for fuel cell vehicles (FCVs), and even AI server applications such as eFuses. Additionally, they are ideal for EV charging stations, showcasing their adaptability in meeting various industrial needs.
Sales Information and Product Launch
Regarding availability, the DOT-247 will be offered in OEM quantities, beginning its journey in September. Importantly, products that carry AEC-Q101 qualification are set to commence sample shipments starting in October, ensuring that partners can begin testing and integrating these groundbreaking technologies without delay.
Comprehensive Support for Adoption
ROHM remains dedicated to ensuring smooth transitions to their advanced solutions. They provide extensive application-level support, which includes the utilization of in-house motor testing equipment. Supporting materials featuring comprehensive simulations and robust thermal designs are at the disposal of developers, facilitating rapid evaluations and the adoption of DOT-247 products. An evaluation kit focused on double-pulse testing is already accessible, and an additional kit tailored for 3-phase inverters is in preparation, with reference designs expected to be available shortly.
