Solid State Relay Market Dynamics

Driver: Growing adoption of high-tech electronics and automation in consumer electronics industry

The consumer electronics industry includes home electronics, beverage dispensing machines, and office machines. The global consumer electronics market is expected to increase owing to the increasing adoption of hi-tech electronics. Home electronics such as TV, AC, microwave oven, and refrigerator are becoming smarter. The digitization of consumer electronics is also evident in beverage dispensing machines and office machines, such as fax and inverters. The change in consumer behavior toward the adoption of advanced, easy-to-use, and smart technologies has led to a rise in the digitization of consumer electronics. SSR is used in many consumer electronics appliances as a replacement to conventional electromechanical relay (EMR). It is used in consumer electronics such as ovens, HVAC equipment, and coffee vending machines for switching applications and providing protection against electrical surgesHence, the growing adoption of high-tech electronics and automation in consumer electronics is propelling the growth of the solid state relay (SSR) market.

Restraint: Need for safe operating temperature to manage dissipating heat generated by SSR

An SSR does not have moving parts but operates based on the properties of semiconductors. These semiconductors generate heat while operating at the rate of ~1–1.5 W per ampere of load current for AC output SSRs, and 0.2–1.5 W per ampere of load current for DC output depending upon their design. Thus, SSR requires an effective method for dissipating heat. The most common method is the use of an adequate size of a heat sink. Heat sink dissipates the heat generated by SSR into surrounding ambient air and maintains a safe operating temperature while increasing the operating life of the SSR. The heat sinks are made of thermally conductive materials such as aluminum or steel. Heat sinks have a low thermal impedance and work more efficiently if the air flow is maximum. The safe operating temperature is also achieved with the use of small exhaust fans over the heat sinks to keep the air flow constant. Thus, the use of heat sinks or exhaust fans limits the use of SSR independently for applications with more than 5 amps of load. The need for heat sinks to dissipate the heat generated by SSR complicates the designing of an electric circuit, which restrains the use of SSRs
