Solid-state Relay Market Analysis

Output Voltage Segment Analysis

The AC output SSRs in the output voltage segment are anticipated to garner the largest share in the solid state relay market of 65.8% by the end of 2035. The sub-segment’s upliftment is highly propelled by its importance for reliably switching AC loads, such as lights, heaters, and motors, since they provide precise, fast, and silent switching with no moving parts, along with increased reliability. According to an article published by Heliyon in January 2025, the flexible alternating current transmission (FACTS) devices market is valued at USD 1,350.5 million, which is predicted to increase to USD 2,688.4 million by the end of 2032. This is exhibited by a 5.9% growth rate, which is positively impacting the segment’s growth. Besides, the overall segment is comprehensively utilized in industrial automation, home appliances, renewable energy systems, and HVAC, which enhances the segment’s growth.

Input/Output Circuit Segment Analysis

The photo-coupled SSRs segment, which is part of the input or output circuit, is projected to constitute the second-largest share in solid state relay market during the forecast period. The segment’s development is highly fueled by its fundamental design, which uses a photo-sensitive semiconductor and a light-emitting diode (LED) to develop an isolation gap between the high-voltage load output and low-voltage control input. This optical isolation overcomes damaging voltage transients and provides outstanding noise immunity. As a result, this has made this particular SSR category the standard choice for the majority of ICT and industrial applications, wherein signal integrity is paramount. In addition, the cost-effectiveness, compact form factor, and reliability for standard switching activities have also bolstered its position. Therefore, with the presence of such benefits, the segment is poised to gain increased exposure in the overall market.

Current Rating Segment Analysis

The low current (up to 40A) segment under the current rating is expected to account for the third-largest share in the solid state relay market by the end of the stipulated timeline. The segment’s growth is highly propelled by the core of the ICT and digitalized revolution, along with the proliferation of signal switching applications and low-power control. This particular rating range significantly covers the majority of demands in modernized electronics, which include interfacing Programmable Logic Controllers (PLCs) with solenoids and sensors, automating processes in robotics, and controlling signals in telecommunications equipment. These drivers are multifaceted, readily centering around the exponential development of the IIoT, which actively connects countless actuators and low-power sensors. Meanwhile, expansion in data centers has resulted in SSRs managing fan control and board-level power distribution, which is also uplifting the segment’s demand.
