Infineon Expands SiC Manufacturing Capacity to Meet Growing Power Semiconductor Demand in 2026

Infineon Technologies has moved to significantly expand its silicon carbide (SiC) manufacturing footprint, adding new 200mm wafer production lines to address accelerating demand from automotive OEMs and industrial customers transitioning to wide-bandgap power semiconductors.

The expansion represents a major commitment to SiC technology, which offers significant efficiency advantages over traditional silicon IGBTs in high-power applications including EV traction inverters, onboard chargers, and industrial power supplies.

For procurement teams sourcing power semiconductors, Infineon's expanded SiC capacity signals improved availability of wide-bandgap devices that have been on extended lead times as demand outstripped supply. The new 200mm wafer lines will increase output of key SiC MOSFET and diode products.

Our view is that buyers should engage early with Infineon and other SiC suppliers to secure allocation for 2027 production programs, as the transition to wide-bandgap power devices accelerates across automotive and industrial segments.

The wide-bandgap semiconductor market, including SiC and GaN devices, is projected to grow at a compound annual growth rate exceeding 20% through 2030, driven by EV adoption, renewable energy infrastructure, and industrial electrification. Infineon's capacity expansion positions it to capture a larger share of this rapidly growing market.

For distributors and OEMs, the expansion means more competitive pricing and shorter lead times for SiC devices in the medium term, though immediate supply constraints are expected to persist through 2026 as new production lines ramp.
