Bosch has launched its third generation of silicon carbide (SiC) chips, delivering approximately 20% higher performance compared to the previous generation. This advancement strengthens the company’s position as a key technology supplier for the rapidly expanding electric vehicle (EV) market while enabling stronger local semiconductor ecosystems.
Silicon carbide semiconductors switch faster and more efficiently than traditional silicon chips, reducing energy losses in power electronics. This directly translates to longer driving range, faster charging, higher overall system efficiency, and more compact inverter designs in electric vehicles.The new Gen 3 SiC MOSFETs build on Bosch’s proven trench architecture with improvements in on-resistance, switching behavior, ruggedness, and chip size. These enhancements allow automakers to develop more powerful and efficient electric drivetrains suitable for both premium and mass-market vehicles
Bosch has already begun supplying samples of the third-generation chips to global automakers, with series production expected to ramp up in the coming years. The chips are manufactured on modern 200-millimeter wafers, supporting higher volumes and better cost efficiency.
Since starting SiC chip production in 2021, Bosch has delivered more than 60 million SiC chips worldwide. This milestone underscores the company’s manufacturing scale and reliability in the automotive semiconductor space.
Markus Heyn, member of the Bosch board of management and chairman of the Bosch Mobility business sector, stated: “Silicon-carbide semiconductors are the key drivers of electromobility. With our next-generation SiC chips, we’re systematically expanding our technological leadership and helping our customers put even more powerful and efficient electric vehicles onto the road.” Bosch aims to become one of the world’s leading manufacturers of SiC chips
Bosch has specifically highlighted the introduction of these chips in India to support the country’s ambitious EV growth targets. The third-generation technology is expected to deliver tangible benefits to Indian consumers, including longer range, faster charging, and lower total cost of ownership.
Sandeep Nelamangala, Joint Managing Director of Bosch Limited, emphasized the role of this technology in making high-efficiency power electronics more accessible and unlocking the full potential of India’s EV market.By advancing local capabilities and supplying advanced components, Bosch is contributing to the development of a robust domestic EV supply chain and ecosystem in India.
Third-generation SiC chips represent an important step toward making electric vehicles more competitive with internal combustion engines in terms of efficiency, performance, and cost. As EV adoption accelerates globally and in markets like India, technologies like these will be critical in addressing key challenges around range anxiety, thermal management, and power density.With continued investment in production facilities in Germany and the United States, Bosch is positioning itself to meet the surging demand for advanced power semiconductors in the years ahead.
