Insulated-Gate Bipolar Transistor (IGBT) Market to Reach $13.9 Billion by 2035

Insulated-gate bipolar transistor (IGBT) market is projected to expand from $8.8 billion in 2025 to $13.9 billion by 2035, registering a CAGR of 4.8% from 2026 to 2035. Market growth is supported by rising demand for energy-efficient power conversion, electric vehicles, renewable energy systems, industrial automation, and high-capacity electrical equipment. IGBTs are power semiconductor devices that combine the voltage-controlled switching characteristics of MOSFETs with the high-current handling capabilities of bipolar transistors. They are widely used in inverters, motor drives, uninterruptible power supplies (UPS), electric vehicle powertrains, and industrial power conversion systems, where controlled switching and efficient power management are essential.

The expansion of electric mobility is creating additional demand for power semiconductors used in vehicle inverters, charging equipment, and auxiliary electrical systems. According to the International Energy Agency (IEA), global electric car sales exceeded 20 million units in 2025, increasing by 20% compared with 2024 and accounting for approximately one-quarter of new cars sold worldwide. This growing adoption of electric vehicles is supporting the need for efficient power conversion and motor-control technologies, including IGBTs. Although silicon carbide (SiC) devices are increasingly used in selected high-voltage applications, IGBTs remain relevant for automotive auxiliary systems, industrial motor drives, renewable energy inverters, and other applications requiring a balance of efficiency, reliability, and cost.

Renewable Energy Expansion and Power Conversion Support IGBT Market Growth

The expansion of renewable energy infrastructure is increasing demand for power semiconductor devices used in electricity conversion and grid integration. According to the International Renewable Energy Agency (IRENA), global renewable power capacity increased by 692 GW in 2025, representing annual growth of 15.5%. Solar power accounted for approximately 510 GW of the additions, highlighting the growing deployment of solar photovoltaic systems and the associated need for efficient power conversion technologies.

IGBTs are used in solar inverters to convert direct current generated by photovoltaic panels into alternating current suitable for electrical grids and connected equipment. They also support wind-power converters, industrial motor drives, uninterruptible power supply (UPS) systems, and other high-power applications. Although silicon carbide (SiC) devices are increasingly used in selected high-efficiency, high-voltage applications, IGBTs remain relevant where switching performance, current handling, reliability, and system cost must be balanced. Continued investment in renewable energy infrastructure and industrial electrification is therefore supporting demand for both discrete IGBTs and integrated power modules.

Discrete IGBTs Address Compact Power Control and Industrial Switching Requirements

The Discrete IGBT segment serves applications requiring individual power switching components rather than multiple IGBT chips integrated into a single module. These devices are used in motor control, power supplies, welding equipment, household appliances, solar inverters, and electric vehicle auxiliary systems. Their voltage ratings, current-handling capabilities, switching characteristics, and package configurations allow designers to select components according to circuit requirements and thermal constraints. STMicroelectronics offers discrete STPOWER IGBTs across voltage ratings ranging from 300 V to 1,700 V, with products intended for industrial and automotive applications. Its portfolio includes devices for general-purpose inverters, motor control, HVAC systems, UPS, solar inverters, traction inverters, and electric vehicle charging equipment. The company also offers automotive-qualified IGBTs and devices with integrated antiparallel diodes for power dissipation and thermal management.

ROHM Semiconductor also supplies discrete IGBTs and bare-die products across multiple voltage classes, including 650 V and 1,200 V devices. Its product portfolio addresses electric vehicle auxiliary equipment, industrial inverters, air conditioning, welding equipment, and power conversion systems. These product offerings illustrate how discrete IGBTs support application-specific power control, while manufacturers continue to develop lower-loss switching structures and device configurations for improved electrical efficiency and thermal performance.
