Thyristor Global Market Report 2026

A thyristor is a semiconductor switching device that regulates electrical current flow within a circuit. It contains multiple alternating layers of conductive material and remains active once triggered until the current falls below a defined threshold. Thyristors are widely applied in managing high voltage and high current power systems.

The main types of thyristors include unidirectional thyristors, bidirectional thyristors, and other types, while device categories include silicon controlled rectifiers, gate turn off thyristors, bidirectional triacs, reverse conducting thyristors, and asymmetric thyristors. Unidirectional thyristors are semiconductor devices that permit current flow in only one direction when activated by a gate signal. Voltage ratings are classified as less than 500 MW, 500 to 1000 MW, and above 1000 MW and triggering methods include electrical gate triggered, light triggered, and pulse transformer triggered. These thyristor solutions are applied across industrial drives and motor control, high voltage direct current and flexible alternating current transmission systems, renewable power conversion such as solar and wind, transportation including rail traction and marine, automotive including on board chargers and electric vehicle powertrain, consumer electronics and appliances, and aerospace and defense.

Tariffs on imported semiconductor materials, power electronic components, and high-voltage modules are impacting the thyristor market by raising manufacturing and procurement costs, particularly affecting segments such as HVDC systems, renewable power conversion, and industrial motor control. Regions like North America, Europe, and Asia-Pacific that rely on imported high-voltage components are most affected. While tariffs increase costs, they also encourage domestic production, localized supply chains, and innovation in cost-efficient, high-reliability thyristor solutions, potentially strengthening regional manufacturing capabilities.

The thyristor market size has grown strongly in recent years. It will grow from $1.7 billion in 2025 to $1.79 billion in 2026 at a compound annual growth rate (CAGR) of 5.2%. The growth in the historic period can be attributed to rising industrial automation, increasing deployment of hvdc systems, growing adoption of motor drives, expansion of renewable energy projects, rising demand for high-voltage power control.

The thyristor market size is expected to see strong growth in the next few years. It will grow to $2.21 billion in 2030 at a compound annual growth rate (CAGR) of 5.4%. The growth in the forecast period can be attributed to growing electric mobility adoption, increasing deployment of smart grids, rising renewable power installations, expansion of rail traction and marine electrification, increasing adoption of ev onboard chargers and powertrains. Major trends in the forecast period include increasing adoption of high-power thyristors in hvdc and facts, rising demand for thyristor-based renewable power conversion systems, growing integration of light triggered thyristors (ltt), expansion of bidirectional thyristor applications in ac switching, rising focus on automotive and ev powertrain applications.

The increasing need for renewable energy is expected to accelerate the thyristor market in the coming years. Renewable energy refers to electricity generated from naturally replenishing resources such as solar, wind, and hydropower, reducing reliance on fossil fuels and lowering emissions. Demand is rising as governments and industries emphasize sustainable energy generation, climate action, and energy security. Thyristors contribute to renewable energy systems by enabling efficient power regulation, voltage control, and high capacity switching in converters and inverters used in solar and wind installations. In March 2025, the International Renewable Energy Agency reported that renewable capacity additions reached 585 gigawatts in 2024, accounting for 92.5 percent of total power expansion and bringing global capacity to 4448 gigawatts. Therefore, the rising demand for renewable energy is driving the growth of the thyristor market.

Prominent companies in the thyristor market are focusing on developing innovative solutions such as high performance gate drivers to enable efficient and space saving alternating current appliance designs. Ultra compact thyristor gate drivers are devices that integrate isolation and control features within a small form factor, supporting high electrical isolation, noise immunity, and efficient triggering for household and industrial alternating current applications. For instance, in February 2026, STMicroelectronics, a Switzerland based semiconductor company, launched the STSID140 12 ultra compact thyristor gate driver designed for space constrained alternating current powered appliances. The device features an integrated isolation transformer within a compact package, providing strong insulation and reliability while reducing board space and supporting zero cross and phase angle control modes for large thyristors, triacs, and solid state relays.

In December 2025, ABB Ltd., a Switzerland based electrification and automation technology company, acquired the power electronics business of Gamesa Electric from Siemens Gamesa for an undisclosed amount. Through this acquisition, ABB aims to reinforce its presence in renewable power conversion by broadening its portfolio of wind converters, battery energy storage systems, and utility scale solar inverters while strengthening global service capabilities. Gamesa Electric is a Spain based company that manufactures power electronic components incorporating thyristor technology for wind turbine converters, solar inverters, and energy storage systems.
