TechInsights predicts that global automotive power semiconductor vendors' revenue will decline by approximately 6.4% year-on-year in 2025, falling to approximately $13.2 billion, accounting for about 17.8% of the entire automotive semiconductor market. In the 2025 automotive semiconductor vendor market share analysis, power devices will remain one of the largest device categories, but unlike processors and memory, the trend of power semiconductors is contrary to the overall market trend. This shift has significant strategic implications, indicating that the automotive semiconductor market is no longer primarily driven by electrification factors during periods of shortage, and suppliers with a high proportion of traditional power product deployments will be more vulnerable in 2025.
Infineon will lead the automotive power semiconductor market in 2025 with a market share of approximately 24.2%, followed by STMicroelectronics with 15.0%, Bosch with 12.3%, Texas Instruments with 11.9%, and ON Semiconductor with 7.7%. The top five suppliers collectively accounted for approximately 71.1% of the global automotive power semiconductor market in 2025. This ranking reflects both the high concentration of leading companies and the uneven development of the market in 2025. Despite a year-on-year revenue decline, Infineon maintained a clear leading position; while STMicroelectronics and ON Semiconductor, due to their over-reliance on power business and weak performance, experienced more significant market share losses. In contrast, Bosch and Texas Instruments showed relatively stronger resilience.
The market landscape can be clearly understood from the technology segmentation. Among suppliers with data on specific models, power integrated circuits (PICs) remain the largest power segment in 2025, accounting for approximately 41.6% of the revenue of the statistically analyzed segments; followed by MOSFETs at 26.4%; IGBTs at 16.3%; and silicon carbide MOSFETs at 14.8%. Gallium nitride high electron mobility transistors (GaN HEMTs) still accounted for a very low percentage, only about 0.3%, but as a noteworthy technology direction, their strategic significance remains prominent. The key conclusions of this report, focusing on key product categories, are: IGBT revenue declined significantly, traditional MOSFETs weakened, while silicon carbide devices showed greater resilience. This indicates that even with short-term market pressure, the trend of automotive companies transitioning to higher-voltage, higher-efficiency new energy vehicle architectures remains unchanged.
In summary, 2025 performance data shows that power semiconductors remain a fundamental core market for automotive electronics, but have entered a phase of technological differentiation and intensified structural selection. The electrification dividend is no longer evenly distributed among all power semiconductor manufacturers. Instead, a supplier's market position increasingly depends on the adaptability of its technology portfolio, voltage platform, and vehicle platform transformation, especially given the continued strict cost control by OEMs and the increasingly precise application of wide-bandgap devices.
