The Role of Silicon Carbide in a Sustainable Tech Revolution
The global shift toward clean energy and smarter mobility is accelerating the demand for high-efficiency power solutions. One of the most promising innovations enabling this transition is silicon carbide (SiC) technology. As traditional silicon reaches its limits in high-performance environments, SiC offers enhanced energy efficiency, higher voltage tolerance, and compact design benefits. Electric vehicles (EVs), renewable energy systems, and industrial automation are among the sectors reaping these rewards. In this space, Infineon Technologies AG is setting new standards, with its pioneering SiC superjunction (TSJ) technology leading the charge in EV adoption and industrial efficiency.
Infineon’s SiC TSJ Technology Redefines Power Efficiency
Infineon has long been a leader in SiC innovation. Its new trench-based SiC superjunction (TSJ) concept merges two advanced technologies—trench MOSFET design and superjunction architecture. This hybrid boosts efficiency and minimizes system size. It enables high-performance applications to reach new levels of energy savings and power density. Infineon’s CoolSiC™ range now spans 400 V to 3.3 kV, supporting electric vehicle drivetrains, solar energy systems, EV chargers, and high-power inverters. The 1200 V SiC TSJ devices are among the first to roll out, delivering compact solutions without sacrificing power or safety.
Game-Changing Benefits for EV and Industrial Design
One key advantage of Infineon’s TSJ technology is its ability to handle higher currents—up to 25% more—without compromising short-circuit reliability. It also improves *RDS(on)A by up to 40%, significantly raising power density. This translates to smaller, lighter systems with fewer parallel components. Designers benefit from reduced cooling needs, simpler architectures, and lower overall costs. The automotive sector stands to gain the most, with traction inverters that are both more efficient and scalable. Infineon’s ID-PAK package, supporting up to 800 kW, offers the flexibility required for next-generation EV platforms.
Supporting Sustainable Mobility and Smart Industry
As the global leader in automotive semiconductors, Infineon continues to shape the future of sustainable mobility. The integration of SiC TSJ devices helps vehicle manufacturers meet strict emissions and efficiency targets. Hyundai Motor Company is one of the early adopters, working closely with Infineon to enhance its electric vehicle designs. Beyond EVs, the same technology offers transformative benefits in industrial systems, such as renewable power grids, energy storage, and traction drives. These innovations support a broader transition toward low-carbon technologies across multiple sectors.
Infineon Sets the Benchmark for Next-Gen Power Electronics
With more than 25 years of expertise in power semiconductor innovation, Infineon is once again proving its leadership. By merging its trench MOSFET and superjunction experience, it delivers solutions tailored for tomorrow’s electric and industrial landscapes. The launch of SiC TSJ devices not only advances electric vehicle performance but also simplifies system integration, making clean energy systems more practical and cost-effective. Infineon’s commitment to expanding its CoolSiC™ portfolio promises continued breakthroughs that power a smarter, greener future.
