The global digital isolator market size was valued at USD 2.12 billion in 2021 and is projected to grow from USD 2.22 billion in 2022 to USD 3.88 billion by 2029, exhibiting a CAGR of 8.3% during the forecast period. Asia Pacific dominated the global market with a share of 39.5% in 2021.

The global COVID-19 pandemic has been unprecedented and staggering, with digital isolator experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. Based on our analysis, the global digital isolator market exhibited a decline of 2.6% in 2020 as compared to 2019. Digital isolators are electronic chips that transfer digital signals using the isolation barrier. These isolators employ radio frequency coupling techniques that transmit digital information across the isolation barrier. It acts as a substitute for optocouplers. Texas Instruments Inc. offers several isolator chips, such as ISO1042-Q1, an isolated CAN transceiver with 70 V fault protection and varying data rates. It is comparatively less prone to error and faster in speed for data transfer.

It has many applications, including gate drivers, DC-DC converters, ADCs, USB, and other communication devices. These isolators are used in automotive, medical devices, telecommunications, and industrial segments.

The rise in demand for noise-free consumer electronics and the increased usage of advanced technology-based connected devices drive the growth of isolator products. Also, rising investments and adoption of IoT devices have propelled the global demand for isolator products. According to the World Economic Forum Report in 2020, IoT investments among businesses reached USD 832 billion, and consumer spending on IoT solutions reached USD 236 billion in 2020. Such an increase in the adoption of connected devices and IoT solutions around the globe has created a massive demand for digital isolation products. Digital isolation is widely used in consumer electronics and IoT-connected appliances for easy information transfer.


Closure of Manufacturing Facilities Owing to Government Restrictions Hinders Market Growth

The COVID-19 pandemic has shown a downfall in the demand for global isolation products due to the restrictions on manufacturing electronic goods. Amid the pandemic, the consumer electronics components' supply chain was disrupted due to the government's regulations and lockdown measures. The COVID-19 outbreak has declined the demand for consumer electronics raw materials owing to the closure of manufacturing activities. In 2020, the global industrialized economies such as China, India, the U.S., and others registered a decline in manufacturing activities by 2.5%.

However, the manufacturing output remained unchanged among the Asia Pacific economies, owing to the solid production from China, South Korea, and Taiwan. The global market showed a slight decline in the market size by 2.6% in 2020 compared to 2019. In terms of revenue, the market witnessed a decrease in revenue to USD 2.04 billion in 2020.

Post-COVID-19 pandemic, the leading players in the market are developing advanced isolators for industrial automation and data center applications. For instance,

  • In July 2021, Analog Devices, Inc. launched the ADN4624 first series of iCoupler isolators to offer 10 Giga-bits per second bandwidth. It offers four channels at 2.5 Gbps, allowing seamless data transfer in the electrical domains. It enables new system architectures to digitize digital health instrumentations and industrial automation.

The advanced products streamline the designs and easily integrate with isolation for safety. It is a compact solution that encounters the standard medical requirement and isolates the high-fidelity industrial automation requirements.
