EV Sales Surpass 20 Million as the Automotive Grade Silicon Carbide Components Market Enters a New Growth Phase in 2026

Automotive industry is entering a new phase of electrification in which improving battery capacity alone is no longer sufficient to deliver better driving range, faster charging and higher vehicle performance.

Automakers are increasingly focusing on power conversion efficiency, thermal management and compact electrical architectures. This shift is strengthening the importance of the Automotive Grade Silicon Carbide Components Market, particularly as manufacturers introduce higher-voltage electric vehicle platforms and advanced traction inverter systems.

Silicon carbide (SiC) components, including MOSFETs, Schottky diodes, power modules and semiconductor substrates, are becoming important building blocks in modern electric vehicles. Compared with conventional silicon-based devices, SiC technology can operate at higher switching frequencies and temperatures while reducing power losses. These characteristics help manufacturers develop smaller and more efficient onboard chargers, DC/DC converters and traction inverters.

Higher-Voltage EV Platforms Are Changing Component Requirements

The transition from 400V to 800V and 900V electrical architectures is creating new requirements for automotive-grade power semiconductors. Higher-voltage systems can support faster charging and improved power delivery, but they also require components capable of handling demanding electrical and thermal conditions.

• A notable development emerged in April 2026 when onsemi and Geely expanded their collaboration to integrate EliteSiC technologies into vehicles based on Geely’s SEA-S architecture. The partnership supports 900V electric vehicle systems, demonstrating how semiconductor manufacturers are becoming involved in vehicle platform development at an earlier stage.

This shift is also influencing component selection. Automotive manufacturers are evaluating voltage ratings, switching losses, thermal resistance, packaging dimensions and long-term reliability when selecting SiC devices for new vehicle generations.

Automotive Manufacturers Are Moving SiC Into Production Vehicles

• The adoption of silicon carbide is becoming increasingly visible in commercial vehicle programmes rather than remaining limited to technology demonstrations.
• In February 2026, Infineon announced that its CoolSiC MOSFETs had been selected for Toyota’s updated bZ4X, supporting the onboard charger and DC/DC converter.
• Another important development came in September 2026, when ROHM confirmed that its silicon carbide chips were being used in BMW’s Neue Klasse electric powertrain architecture.
• These developments illustrate how automotive-grade SiC components are entering different vehicle platforms and power electronics applications.
• For suppliers, production-level integration creates opportunities to develop long-term relationships with automakers and Tier 1 suppliers. However, qualification requirements remain demanding, with manufacturers expected to demonstrate consistent electrical performance, durability and reliability under automotive operating conditions.

200mm Wafer Manufacturing Is Becoming a Strategic Priority

Manufacturing scalability is another important development shaping the industry. As demand for SiC power devices expands, semiconductor companies are focusing on improving wafer quality, production yields and manufacturing economics.

• In October 2026, Infineon and Wolfspeed announced a multi-year agreement covering 200mm silicon carbide wafers. The arrangement supports Infineon’s transition from 150mm to 200mm SiC manufacturing and strengthens its access to advanced substrate technology.

Larger wafers can provide more usable die area per wafer, creating opportunities to improve production efficiency and reduce manufacturing costs. However, achieving consistent crystal quality, reducing defects and maintaining reliable yields remain important technical considerations.

For automotive customers, these developments matter because dependable component availability and manufacturing consistency are essential when scaling vehicle production across multiple platforms.

Thermal Performance and Packaging Are Influencing Product Design

As electric vehicle power systems become more compact, component packaging and heat dissipation are gaining importance. SiC devices must operate reliably under demanding temperature conditions while supporting higher power density and smaller system dimensions.

• In May 2026, Infineon introduced a 1300V HybridPACK Drive SiC module designed for continuous operation at temperatures up to 205°C. This illustrates the industry’s focus on extending thermal operating capabilities for demanding automotive applications.

Packaging innovations are also influencing product development. Manufacturers are exploring advanced cooling structures, compact power modules and improved interconnection technologies to manage heat more effectively. These improvements can help reduce system dimensions while supporting the performance requirements of next-generation electric drivetrains.

The Automotive Grade Silicon Carbide Components Market Is Expanding Its Technology Scope

The market’s development is no longer determined only by the number of electric vehicles being produced. It is increasingly connected to the electrical architecture, charging capability, inverter efficiency and power density of individual vehicle platforms.

• In 2025, global electric car sales exceeded 20 million units, representing approximately one-quarter of new car sales worldwide. This expanding vehicle base provides an important foundation for the adoption of advanced power semiconductors.
• As automakers move towards 800V and 900V platforms, suppliers are likely to face growing demand for automotive-qualified MOSFETs, high-voltage modules, advanced substrates and integrated power solutions.
• At the same time, wafer manufacturing improvements and thermal-management innovations will influence product competitiveness.

The next phase of the Automotive Grade Silicon Carbide Components Market will therefore depend on how effectively semiconductor manufacturers translate material-level advantages into reliable, scalable and production-ready automotive solutions.
