A small footprint of discrete power MOSFETs plays a critical role in achieving space savings, cost reduction, and easy-to-design applications. Additionally, higher power density can lead to layout routing flexibility and overall system size reduction. By expanding the current PQFN 2×2 portfolio with the new best-in-class OptiMOS™ power MOSFETs, Infineon Technologies AG offers benchmark solutions optimized for efficiency and performance in a small footprint. The new products are ideal for applications like synchronous rectification in switched mode power supplies (SMPS) for servers, telecom, and portable- and wireless chargers. Additional applications also include electric speed controllers for small brushless motors in drones.
The new OptiMOS 6 40 V and OptiMOS 5 25 V and 30 V power MOSFETs further optimize the proven OptiMOS technology for high-performance designs. They offer leading-edge silicon technology, package reliability, and superior thermal resistance (R thJC, max = 3.2 K/W) in the ultra-small PQFN 2×2 mm² package. The new devices combine industry-leading low on-resistance R DS(on) with industry-leading figures of merit (FOMs, Q G and Q OSS) for outstanding dynamic switching performance. As a result, MOSFETs with ultra-low switching and reduced conduction losses ensure optimal energy efficiency and power density, all while simplifying thermal management.
With the compact PQFN 2×2 mm² package outline, the OptiMOS power switches enable an improved system form factor with smaller, more flexible geometric outlines for end-user applications. The MOSFETs facilitate reliable system design with less need for paralleling, significantly reducing space and system cost.

The European Commission has approved the “Important Project of Common European Interest on Microelectronics and Communication Technologies” (IPCEI-ME/CT) with the aim of initiating complex and investment-intensive projects that could not otherwise be realized. This involves 68 projects from 14 member states – and two of those comes from Semikron Danfoss.
Semikron Danfoss is planning the further development of diodes based on thin-wafer technology and the development of a new edge structure – as well as the establishment of automotive module production based on Direct Press Die technology in Nuremberg, a continuation of the activities from the IPCEI on Microelectronics project. And in Slovakia, development activities and an expansion of production for industrial modules are planned.
Projects funded under the IPCEI -ME/CT will enable the development of new technologies and products that will make a decisive contribution to the further reduction of CO2 emissions and will secure growth and jobs in Europe. The Semikron Danfoss projects address the objectives of the European Union to strengthen competitiveness and security of supply in key technologies for both the digital and the green transformation process.
Power semiconductors are an important multiplier along the value chain of many products. The projects also aim to expand European cooperation with universities and research institutes as well as suppliers. The member states are now starting the implementation process and will determine the requirements of the projects based on the EU decision. Thanks to the prior approval of the early start of the initiatives, the projects have already been launched. The official funding commitment from the federal government and the state of Bavaria is expected shortly for Germany.

Silicon Carbide allows for more efficient, smaller, and more capable power conversion systems but getting the most out of these wide-bandgap devices requires intentional selection of everything around the switch. One of the most important parts of the system is the gate driver. The gate drive solution directly impacts the switching efficiency of the SiC MOSFET as well as can have features to make systems more reliable like Miller Clamp and Short Circuit Protection.
From the protection features available on the market today, to the robustness of isolated gate driver solutions, this training will teach about the intricacies of Silicon Carbide needs in gate drivers, the variety of gate drivers available, and the benefits of the various features that gate drivers can provide to the system designer.

Wolfspeed, Inc. announced that CEO Gregg Lowe has been elected to serve on North Carolina Agricultural and Technical State University’s (N.C. A&T) Board of Trustees. N.C. A&T is the nation’s No. 1-ranked historically black college or university (HBCU).
“North Carolina A&T is proud of our continued strong partnership with Wolfspeed and the appointment of CEO Gregg Lowe to our Board of Trustees,” said N.C. A&T Chancellor Harold L. Martin, Sr. “Gregg’s leadership and extensive science and technology background will serve as a vital resource for our prestigious university. I look forward to working with him as we provide new opportunities for our students to pursue the next generation of careers in the green economy, drive innovation and look to solve the problems of both today and tomorrow.”
“I am excited to join the North Carolina A&T Board of Trustees and to serve their students and community,” said Lowe. “Wolfspeed firmly believes in the power of students to change the world, and I’m eager to further strengthen our relationship while working together to usher in the next generation of scientists, technologists and innovators.”
Wolfspeed and N.C. A&T share a rich history of partnership and collaboration. In 2020, Wolfspeed committed $4 million over five years to the HBCU, the single largest donation in the university’s history at that time, to create the Wolfspeed Endowed Scholars Program.
The two entities worked together to establish comprehensive education and training curricula and cutting-edge research and innovation programs. This partnership has opened opportunities for undergraduate and graduate credentials in silicon carbide semiconductor manufacturing, as well as training and career advancement programs for existing semiconductor manufacturing workers.
During President Biden’s visit to Wolfspeed headquarters earlier this year, Wolfspeed announced the continuation of this collaboration with their intent to apply for CHIPS and Science Act funding to build a new research and development facility on North Carolina A&T’s campus. The R&D facility will be focused on silicon carbide to support the next generation of advanced compound semiconductors.

In static switching applications, power designs focus on minimizing conduction losses, optimizing thermal behavior, and achieving compact and lightweight systems while ensuring high quality at a low cost. To meet the needs of next-generation solutions, Infineon Technologies AG is expanding its CoolMOS™ S7 family of high-voltage superjunction (SJ) MOSFETs.
The devices are aiming at SMPS, solar energy systems, battery protection, solid-state relays (SSR), motor-starters and solid-state circuit breakers, as well as PLCs, lighting control, HV eFuse/eDisconnect, (H)EV on-board chargers.
The portfolio extension includes innovative QDPAK top-side cooling (TSC) packages and offers a wide range of features in a small footprint. This makes it highly advantageous for low-frequency switching applications while optimizing cost positioning.
Thanks to the novel high-power QDPAK packaging, they offer an R DS(on) of only 10 mΩ, which is the lowest on the market in this voltage class and the lowest in SMD packages. By minimizing conduction losses of the MOSFETs, the CoolMOS S7/S7A solutions contribute to higher overall efficiency and provide an easy and cost-optimized way to improve system performance.
The CoolMOS S7 power switches also effectively manage heat dissipation with improved thermal resistance. Thanks to the innovative and efficient QDPAK packaging, they also reduce or even eliminate the need for heat sinks in solid-state designs, resulting in more compact and lighter systems.
The MOSFETs are available in both top-side and bottom-side variants, and feature high-pulse current capability, enabling them to handle sudden surges of current. In addition, they exhibit body diode robustness to ensure reliable operation during AC line commutation.
With fewer components required, they reduce part count, resulting in flexible system integration, lower BOM costs, and total cost of ownership (TCO). In addition, these MOSFETs enable shorter reaction times, particularly when breaking a current, facilitating smoother and more efficient operation.
