Global Market Size, Forecast, and Trend Highlights Over 2024-2036

Digital Isolator Market size is anticipated to reach USD 84 Billion by the end of 2036, growing at a CAGR of 8% during the forecast period i.e., 2024-2036. In the year 2023, the industry size of digital isolators was over USD 11 Billion. To isolate machines from electricity and disrupt current flow patterns, there is an increasing trend of integrating digital isolation devices into a wide variety of equipment. This is often done to address the challenge confronted by conclusion clients and producers where they see to run their offices and gear at low-cost controls, and decrease machine downtime, among others. Digital isolators provide signal isolation and shift levels to see the correct operation of different circuits, in high-voltage equipment. They're also designed to prevent electric shocks for users. The growth of the market in terms of revenue is being driven by this. Digikey announced in 2020 the launch of its industrial communication networks, which are protected by the integration of digital isolators. Digital isolation, based on chip-scale transformers, has been made possible by RS4220/RS485 transceivers that integrate an isolated DCDC regulator and a three-channel signal isolator on a single chip.

Digital isolators offer a wide range of advantages, including benefits in terms of size, speed reduced energy consumption, reliability, and ease of integration into the module as compared to optocouplers. In the past, it has been difficult for designers to choose a suitable isolation barrier system used in medical modules or industry applications due to limited options.

Digital Isolator Sector: Growth Drivers and Challenges

Growth Drivers

  • Demand for Noise-Free Electronics and Electric Circuits - The request for noise-free electronic and electrical circuits has expanded drastically. Ground circles are one of the foremost common sources of undesirable clamor in electrical and electric circuits, which can cause them to glitch. When two associated terminals of a circuit have contrasting ground possibilities, a ground circle is generated. The current stream within the interconnection is a result of this potential distinction, coming about in balanced mistakes. Ground circles are broken with advanced isolators, which guarantee that all circuits have the same ground potential. They hinder the galvanic way between diverse ground possibilities permitting analog signals to pass through circles. Electrical commotion initiated by AC coherence is moreover disposed of by these gadgets. Aside from causing circuit harm, undesired conducted clamor caused by an alter in ground potential can cause an electric stun to clients. 
  • Growing Adoption of Industrial Robots and Consumer Electronics - A major trend in the market is a growing acceptance of Industrial Automation within the manufacturing sector. As a result of the ground loop in industrial automation components, this isolator eliminates errors. It's capable of low latency, noise reduction, and high data transfer speeds. Through mergers and acquisitions strategies, several major players have increased their production capacity by setting up innovative isolators. For example, in July 2021, Skyworks Solutions Inc. acquired Silicon Laboratories's infrastructure and automotive business for a valuation of around USD 2.7 billion. The customer base of the semiconductor industry has been diversified by this acquisition.


  • High Manufacturing Costs and Fluctuating Prices of Raw Materials - The growth of the digital isolator market is hindered by increasing production costs for isolation products as well as changes in resource pricing. The global market is dominated by several small and medium-sized players, with the largest market shares acquired by the leading players. In addition, according to the industrial requirement, the price of the raw materials needed for the production of these isolation products varies. The growth of the world market is hindered by these factors.
  • The inability of Digital Isolators to Transmit Low-Frequency Signals Without Modulators is Expected to Hamper the Market Expansion in the Projected Period
  • The High Cost of Integrating Digital Isolators Compared to Traditional Opt couplers is Predicted to Pose Limitations on Market Growth in the Future
