The digital isolator market is projected to grow at a CAGR of 12.55% to reach US$624.889 million in 2028 from US$273.159 million in 2021.

A digital isolator is an electronic component that provides electrical isolation between two circuits while allowing digital signal communication between them. It is commonly used in applications where two circuits operate at different voltage levels or have different grounds, and there is a need to transfer data or signals between them. Digital isolators are used in various applications, including industrial automation, power electronics, medical devices, and telecommunications. One of the primary benefits of digital isolators is their ability to provide galvanic isolation, which is the complete separation of two circuits electrically. Galvanic isolation is essential in applications with a risk of electrical noise or ground loops that can cause errors, damage, or safety hazards. Digital isolators use various isolation techniques, including magnetic, capacitive, and optical coupling, to ensure high reliability and performance.

The digital isolator market is driven by increasing demand for industrial automation, growth in renewable energy sources, and growing demand for medical devices.

• Increasing Demand for Industrial Automation- The demand for automation in various industries such as automotive, oil and gas, and manufacturing are driving the need for digital isolators. Digital isolators are used in industrial automation to provide electrical isolation between control systems and equipment, preventing electrical noise and ground loops. The industrial automation sector is expected to grow significantly in the coming years, creating a huge demand for digital isolators. According to the International Federation of Robotics (IFR), the sales of industrial robots have experienced a robust recovery, with a new all-time high of 486,800 units being shipped globally, marking a substantial increase of 27% compared to the previous year.
• Growth in Renewable Energy Sources- The shift towards renewable energy sources such as solar and wind power drives the demand for digital isolators. These sources generate DC power, which needs to be converted into AC power for use in the grid. Digital isolators are used in power electronics to isolate the DC and AC circuits, ensuring safe and reliable power transmission. The increasing adoption of renewable energy sources is expected to boost the demand for digital isolators in the coming years. According to the International Renewable Energy Agency (IRENA), by the end of 2022, the global capacity of renewable energy generation totaled 3372 Gigawatt (GW), reflecting a remarkable growth in the renewable energy sector, with a record addition of 295 GW or 9.6% from the previous year. Furthermore, an impressive 83% of all power capacity added in the past year was generated through renewable sources.
• Growing Demand for Medical Devices- The growing demand for medical devices drives the need for digital isolators. Digital isolators are used in medical devices such as patient monitors, electrocardiogram machines, and ultrasound equipment to provide electrical isolation between the patient and the equipment. This ensures patient safety and prevents electrical noise and interference. The demand for medical devices is expected to increase with the aging population, driving the growth of the digital isolator market.

Market Developments:

• In July 2021, Analog Devices introduced its new iCoupler digital isolator, the ADN4624. It delivers a total bandwidth of 10 Gigabits per second, positioning itself as one of the earliest in a new series of isolators. The compact device was intended to provide seamless data transfer in the electrical domain, suitable for various applications, including digital health, instrumentation, and smart industry. The ADN4624 offers four isolated LVDS channels of 2.5Gbps, precision timing, and robust isolation for full ADC performance and resolution. In addition, it provides simplified connectivity, adheres to medical standards, and eliminates the need for specialized and cumbersome fiber solutions.
• In July 2022, Navitas Semiconductor purchased VDD Tech, a Belgium-based company specializing in developing digital isolators for power conversion in the next generation. The acquisition was expected to enable stable, reliable, efficient power conversion at MHz+ switching speeds and deliver size, weight, and system-cost improvements in high-power markets such as consumer, motor drive, solar, data center, and electric vehicles. VDD Tech’s proprietary modulation technique allows for very-high-voltage-isolation capability and low-jitter digital communication for isolated-driver control and analog-sensing feedback. The acquisition was expected to create an additional market opportunity of $1 billion annually as VDD Tech’s isolation technology complements Navitas’ growing power-and-control integration strategy. High-power products resulting from the acquisition are set to launch in 2023.

Based on type, the capacitive coupling segment will witness modest growth over the forecast period.

Capacitive coupling is a standard digital isolator technology used in various applications, including industrial automation, medical devices, and automotive systems. The growth of the capacitive coupling digital isolator market can be attributed to increasing demand for noise-free electronic devices, the rise in renewable energy production, and the need for enhanced safety and protection in the healthcare sector.

Americas accounted for a significant share of the global digital isolator market.

Based on geography, the digital isolator market is segmented into the Americas, Europe Middle East and Africa, and Asia Pacific.

The digital isolator market in the Americas is expected to experience steady growth during the projected period, primarily driven by the increasing demand for industrial automation and the development of the renewable energy sector. The United States is the major market in the region due to the high adoption rate of advanced technologies and the presence of prominent players in the market. The automotive sector is also expected to contribute to the growth of the digital isolator market in the Americas, owing to the increasing demand for electric vehicles and the need for high-voltage isolation in battery management systems. Additionally, the medical industry is another significant end-user of digital isolators, as it requires reliable and high-performance solutions for accurate data acquisition and signal transmission. The ongoing advancements in IoT and the rise of smart homes and cities are also anticipated to provide lucrative opportunities for the digital isolator market in the region.
