PowerAmerica Member Monolith Announces 1200V SiC Diode Samples

Monolith Semiconductor, Texas-based startup and PowerAmerica member, has announced the availability of engineering samples of 1200V, 5A and 10A SiC Schottky diodes in TO-220 packaging. The diodes, which reduce losses by more than 50 percent compared to silicon diodes, are manufactured at X-Fab Texas’ 150mm SiC foundry.

According to the company, the collaboration with the U.S. Department of Energy and PowerAmerica has been key in achieving this milestone.

“DOE and PowerAmerica have taken the baton and supported XFab to create a center of excellence in SiC manufacturing in the U.S.,” said Monolith CEO Sujit Banerjee.

 Funding from DOE and PowerAmerica enabled XFab, a former silicon foundry, to reconfigure its equipment in order to fabricate silicon carbide power electronic devices.  Today, more than six U.S. companies are using the new capability.

Federal Grant Will Help Grow PowerAmerica

The North Carolina Manufacturing Extension Partnership (NCMEP) has been awarded a two-year, $1 million federal grant to help cultivate the growth of the PowerAmerica Institute.

The grant, awarded by the National Institute of Standards and Technology (NIST), will enable NCMEP to work with PowerAmerica and its expanding network of project partners to grow the wide bandgap semiconductor technology sector, accelerate the production of valuable goods and services and develop industry-led skills strategies.

Embedding a highly-trained engineer within PowerAmerica will be one of the first items of business under the grant. In addition to serving as a valuable technical resource, the engineer will lead outreach and project development nationally to small- and medium-sized manufacturers in market sectors, like renewable energy and innovative transport systems, where WBG semiconductors could have the most impact.

“We are excited to work more closely with PowerAmerica in order to ensure that the development of this new technology includes our nation’s smaller manufacturers.  With this work, we will also learn more about the other Manufacturing USA institutes and how they can benefit our NC manufacturers,” says NCMEP Director Phil Mintz.

By the close of 2018, Mintz says that he expects to see development of many advanced manufacturing projects between PowerAmerica and small to medium-sized enterprises across the U.S.

PowerAmerica Researcher Dr. Iqbal Husain Featured for Work with SiC EV Inverter

Iqbal_HusainIASN.C. State University is highlighting its own PowerAmerica-funded researcher Dr. Iqbal Husain for his work to design a smaller, more efficient electric vehicle inverter using off-the-shelf wide bandgap silicon carbide components. Read the full article here.

A paper on the new inverter, “Design Methodology for a Planarized High Power Density EV/HEV Traction Drive using SiC Power Modules,” will be presented at the IEEE Energy Conversion Congress and Exposition (ECCE), being held Sept. 18-22 in Milwaukee.

PowerAmerica Now Part of Manufacturing USA

The National Network of Manufacturing Innovation – of which PowerAmerica is a part – has a new name and brand: Manufacturing USA.

The announcement was made by U.S. Secretary of Commerce Penny Pritzker at the annual International Manufacturing Technology Show (IMTS) in Chicago on Sept. 12. Read the full press release here.

Manufacturing USA consists of nine public-private institutes dedicated to securing the nation’s future through manufacturing innovation, education, and collaboration.

PowerAmerica Partnership

In partnership with PowerAmerica, USCi is developing and qualifying SiC Schottky diodes 650V-1200V at XFab’s 6-inch SiC foundry by transferring USCi’s high performance 4-inch processes. Additionally, USCi is developing 1200V SiC MOSFETs in the SiC foundry. Production release for both products is planned for early 2017. 

USCi expertise can benefit members in many ways such as:

  • Providing access to class leading Schottky Diodes
  • Partnering in supplying automotive qualified die to module customers
  • Providing access to the lowest resistance switch technologies in the industry
