Silicon MOSFET delivers 150V and 200V with industry-leading FoM

24-07-2025 | iDEAL Semiconductor | Power

iDEAL Semiconductor's SuperQ technology has entered full production, with the first products being 150V MOSFETs. A family of 200V MOSFETs is sampling.

SuperQ is the first notable advance in silicon MOSFET design in over a quarter of a century, delivering unmatched performance and efficiency in silicon power devices. The architecture breaks through silicon's fundamental barriers to switching and conduction. It almost doubles the n-conduction region (up to 95%) and reduces switching losses by up to 2.1 times versus competing devices.

The structure also enhances resistance and power losses while maintaining the benefits of silicon, including its ruggedness, high-volume manufacturability, and proven dependability at 175C junction rating.

The first product in the company's 150V MOSFET series, iS15M7R1S1C, is a 6.4mΩ MOSFET. It is available immediately in a 5mm x 6mm PDFN package. The SMT package features exposed leads to simplify assembly and enhance board-level reliability.

The 200V family includes the iS20M6R1S1T, a 6.1mΩ MOSFET in a 11.5mm x 9.7mm TOLL package. This has an RDSon of 6.1mΩ, which is 10% lower than the current industry leader and 36% lower than the next best competitor. The company is also sampling 200V MOSFETs in TOLL, TO-220, D2PAK-7L and PDFN packages.

300V and 400V MOSFET platforms are coming soon—voltage classes underserved by today's silicon technologies. The company's upcoming devices are designed to deliver dramatically lower resistance than existing solutions, opening up new possibilities for enhanced efficiency and performance.

"For the past quarter-century, the industry has relied on Reduced Surface Field (RESURF) technologies like Superjunction, but these architectures' performance has plateaued. To achieve the necessary gains in power delivery and efficiency, a new architecture is required and that is SuperQ," said Mark Granahan, CEO and co-founder of iDEAL Semiconductor.

"The demand for higher performing power solutions has never been greater. SuperQ will enable emerging critical applications ranging from industrial automation, AI data centre and the world's electrification trends. Today iDEAL is announcing new levels of cost times performance for the designer's toolbox at 150V – 400V that simply didn't exist."

This innovation is designed for MOSFETs, IGBTs, diodes, power ICs, and even future semiconductor materials, positioning SuperQ as a foundational technology for the next era of power electronics.
