2026 SiC MOSFET Price Surge: A Four-Step Action Guide for OEMs to Secure Supply

Procurement of silicon carbide (SiC) MOSFETs in the bill of materials (BOM) has already incorporated this year's price adjustments. Industry forecasts project that China's SiC device market will reach approximately RMB 11.09 billion in 2026, marking a year-over-year growth of 32.4%—the highest rate globally. Demand is surging far faster than capacity expansion, driven by the widespread adoption of 800V high-voltage platforms, increased SiC usage per photovoltaic inverter (from 1.2 to 2.1 units), and rising demand for bidirectional energy storage converters. Infineon and STMicroelectronics have issued two rounds of price increase notices this year, with domestic manufacturers following suit. This article examines the rationale behind these price hikes, offers market trend forecasts, and provides a four-step procurement action guide covering price locking, dual sourcing, authenticity verification, and spot purchasing.
