1,200-V SiC Half-Bridge Modules Offer Easy Upgrade Path for IGBT-Based Designs
The QSiC Dual3 family of 1,200-V half-bridge MOSFET modules developed by SemiQ Inc. targets motor drives in data center cooling systems, grid converters in energy storage systems, and industrial drivers.
Two of the family’s six devices have an RDS(on) of just 1 mΩ and a power density of 240 W/in.3 from its 62- × 152-mm package. The QSiC Dual3 was created to enable the replacement of IGBT modules with minimal redesign.
All MOSFET die have been screened using wafer-level, gate-oxide burn-in tests exceeding 1,450 V. In addition, the modules feature a low junction-to-case thermal resistance and usher in simplified system design with smaller, lighter heatsinks.

Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.
Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.
Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.
Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
Lee also writes the regular PowerBites series.
