Infineon Showcases SiC Topside-Cooled Power Solutions
Infineon Showcases SiC Topside-Cooled Power Solutions 
At APEC 2026, Infineon Technologies highlighted how next-generation power semiconductors are transforming system design, with a strong focus on silicon carbide (SiC). Speaking from the booth, Peter Friedrich walked through how Infineon is leveraging SiC and advanced packaging to simplify designs while improving efficiency and thermal performance.
Infineon continues to support a broad range of power technologies—including silicon, silicon carbide, and gallium nitride—but SiC is playing a key role in enabling higher power density systems across industrial and automotive applications.
From Stacked Designs to Flat PCB Integration
One of the key demonstrations compared traditional motor drive designs with newer SiC-based solutions. In conventional systems, engineers often need to stack multiple components to achieve the required performance, increasing complexity and limiting thermal efficiency.
With Infineon’s topside-cooled silicon carbide packages, that design approach changes significantly. Instead of stacking components, engineers can place the solution directly onto a single flat PCB. This simplifies layout, reduces system size, and improves overall manufacturability.
Better Thermal Performance and Efficiency
Thermal performance is one of the biggest advantages of this approach. According to Infineon, these topside-cooled packages can deliver up to 60% lower thermal resistance (Rth), allowing for more effective heat dissipation.
That improvement translates directly into higher system efficiency and reduced cooling requirements. Smaller heatsinks, lower thermal stress, and better reliability all contribute to a more optimized design—especially in high-power applications.
What Engineers Need to Know
Designing with topside-cooled SiC devices does introduce some new considerations. Engineers need to account for different thermal paths and packaging characteristics compared to traditional solutions. However, Infineon provides design guidance and resources to help teams make that transition.
While there is an initial learning curve, the long-term benefits make it worthwhile. Once engineers become familiar with the approach, it can be applied across multiple designs, accelerating future development cycles.
Applications Focused on Power Density
The primary application highlighted at the booth was motor drives, where compact size and efficient cooling are critical. By enabling high power density in a smaller footprint, these solutions allow motor control systems to be integrated more directly with the motor itself.
Beyond motor drives, any application requiring high efficiency, compact design, and effective thermal management can benefit—including industrial systems, EV platforms, and data center infrastructure.
Driving the Next Generation of Power Design
Infineon’s showcase at APEC 2026 reinforces the growing importance of silicon carbide in modern power electronics. By combining advanced materials with innovative packaging like topside cooling, the company is helping engineers push the limits of efficiency and integration.
As power demands continue to increase across industries, solutions that reduce size, improve thermal performance, and simplify design will be key—and Infineon is positioning its SiC portfolio to meet those challenges.
