The solid state relay market size is expected to see strong growth in the next few years. It will grow to $2.17 billion in 2030 at a compound annual growth rate (CAGR) of 6.8%. The growth in the forecast period can be attributed to expansion in electric mobility, increasing demand in industrial oem applications, integration with smart and connected devices, advancements in high-power ssr technologies, growing adoption in building equipment and food & beverages sectors. Major trends in the forecast period include miniaturization and compact design, high-speed switching and reliability, energy-efficient power management, enhanced electrical isolation technologies, integration with smart systems.

The growing demand for electric vehicles (EVs) is anticipated to boost the solid-state relay market in the coming years. Electric vehicles are powered by motors that use electricity stored in batteries, operating on electric motors while charging from electric sources rather than relying on fossil fuels like gasoline or diesel. Solid-state relays provide longer operational lifespans compared to mechanical relays and offer superior battery isolation capabilities in EVs. This adoption contributes to a surge in demand for EVs and hybrid vehicles, reflecting a shift from petroleum-based products to more sustainable energy solutions. For example, in April 2024, the International Energy Agency, a France-based intergovernmental autonomous organization, reported that nearly 14 million electric cars were sold worldwide in 2023, accounting for 18% of total car sales, an increase from 14% in 2022. Thus, the rising demand for electric vehicles is driving the solid-state relay market.

Leading companies operating in the solid-state relay (SSR) market are focusing on developing innovative solutions, such as high-endurance, high-temperature-resistant, and compact, energy-efficient designs, to meet growing industrial automation and power control needs. High-endurance refers to a device’s ability to withstand prolonged or repeated use without failure. For example, in August 2024, Littelfuse Inc., a U.S.-based industrial technology manufacturer, introduced its SRP1 Solid-State Relay family, a high-endurance SSR series capable of enduring more than 750,000 life-stress cycles under demanding conditions. The SRP1 series includes ratings from 10 A to 90 A for both AC and DC control, with options for zero-voltage (zero-cross) or random turn-on, IP20 finger-safe protection, and integrated overvoltage protection. These SSRs are well-suited for industrial automation applications (such as packaging machinery and ovens), HVAC systems (including electric heating in air-handling units), and food-and-beverage equipment (such as coffee machines and fryers), providing improved reliability, reduced downtime, and easier installation.

In November 2023, Hongfa Group, a China-based relay manufacturing company, acquired the global relay business of HELLA for an undisclosed sum. Through this acquisition, Hongfa Group aims to strengthen its global presence in relay production and incorporate HELLA’s expertise to align with emerging trends in electric mobility and autonomous driving. HELLA, a Germany-based manufacturing company, provides solid-state relays in which the control signal connects to the input terminals and the load to the output terminals, ensuring voltage and current specifications are properly matched. Safe installation practices and adherence to manufacturer guidelines are essential when working with such components.

Solid-state relays are semiconductor devices akin to electromechanical relays that can control electrical loads without incorporating moving parts. These relays operate without any moving components, using the electrical and optical properties of solid-state semiconductors to achieve input-to-output isolation and switching functions.

These relays are typically available in various mounting types, including panel, PCB (Printed Circuit Board), DIN rail, and other plug-in configurations. Panel-mounted static relays are designed to accommodate wiring using bare cables, crimped cable ends, fork lugs, or ring lugs. They are rated for controlled DC circuit operation and support load voltages ranging from 24 to 300 V AC output. SSRs come in different output configurations such as AC SSR, DC SSR, and AC/DC Output SSR, and they vary in power ratings categorized as low (0-20A), medium (20A-50A), and high (>50A). These devices find applications across various sectors including energy and infrastructure, industrial Original Equipment Manufacturers (OEMs), building equipment, food and beverage industries, automotive and transportation sectors, as well as industrial automation.Asia-Pacific was the largest region in the solid state relay market in 2025.
