A digital isolator is a device that is utilized in order to get a digital signal over a galvanic isolation boundary. They provide the same function as optocouplers, with the exception that optocouplers are significantly sluggish and error-prone for high-speed (1MHz+) digital transmissions.
New York, July 04, 2022 (GLOBE NEWSWIRE) -- Reportlinker.com announces the release of the report "Global Digital Isolator Market Size, Share & Industry Trends Analysis Report By Technology, By Vertical, By Application, By Insulating Material, By Channel, By Data rate, By Regional Outlook and Forecast, 2022 – 2028" - https://www.reportlinker.com/p06289234/?utm_source=GNW
They also leverage a different coupling mechanism than optical links, commonly a transformer or RF link. Although digital isolators are designed to work with solely digital signals, they are routinely used to transport digitized versions of analog signals. In comparison to an optocoupler-based system, the resulting signal chain would have superior bandwidth, precision, and linearity. Because optocouplers are nonlinear and have large unit-to-unit changes (+- 50% of thr signal), the circuit must be immune to these variations or each unit must be properly calibrated.
Multiplexing digital channels all over a single digital isolator line is simple, resulting in net cost savings while using a more expensive isolation technique. To summarize, digital isolators outperform optocouplers in practically every way. Silicon Labs, ADI, TI, Broadcom Corporation, Maxim Integrated, Vicor, Rhopoint Components, NVE, ROHM, and others are some of the key players in this market. Because the major raw material price has remained reasonably consistent in recent years, with the addition of a significant increase in production capacity, the raw material price for Digital Isolators is anticipated to remain stable in the near future. However, improvements in energy prices, transportation costs, and labor compensation will all contribute to lower Digital Isolator costs. Companies are using new technologies and focusing on cost and quality leadership in order to increase profitability. To cut costs and increase quality, organizations are focused on technology innovation, equipment upgrades, and process improvements.
Increasing trends of replacing conventional optocouplers with digital isolators, as well as the rising popularity of noise-free electrical devices and electronics, are some of the primary reasons driving the growth of the digital isolators market. The growing utilization of digital isolators in a variety of industrial applications, such as industrial fieldbuses, motor controllers, and power supply, is likely to fuel market growth. As a result of its rapid data transmission rates along with robust transient immunity, capacitive technology across a digital isolator has a strong global preference. Magnetic field interference is not a problem with capacitive digital isolators. Because of the advantages offered by capacitive digital isolators over inductive and optical technologies, the market for capacitive digital isolators would rise steadily over the forecast period.
The advent of the COVID-19 pandemic majorly impacted the global economy. The COVID-19 infection caused a steep downfall to businesses all over the world irrespective of their sizes. In addition, in order to regulate the spread of the pandemic, various governments all over the world were compelled to enforce lockdown in their nations, which resulted in a temporary industrial shutdown. The industrial closure caused a shortage of various goods and services to people across the world. Moreover, due to the government-imposed travel restrictions, the worldwide supply chain was also significantly disrupted, due to which, various industries witnessed significant losses.
Market Growth Factors
Complies with rigorous automotive safety requirements
Automotive manufacturers all around the world have declared stringent plans to launch new battery electric vehicles, plug-in hybrid electric vehicles, and full-hybrid electric vehicles. The BEV provides a smooth, quiet, and emission-free ride. High-wattage power electronics are becoming important components in the novel electronic drivetrain and battery systems as automobile designs move toward electrification. How to transfer digital data between low voltage battery domain electronics and high voltage battery domain electronics is one of the challenges a designer would confront when developing solutions for automotive xEV applications.
Rising requirement for Isolated Gate Driver
Isolated gate drivers are in high demand because they provide electrical isolation as well as powerful gate drive capacity, which is essential for system architectural safety and robustness. Isolated gate drivers offer reliable control over switching qualities for metal oxide semiconductor field-effect transistor configurations, as well as high switching speed and system size constraints, which are required for power switch systems, such as silicon carbide and gallium nitride.
Market Restraining Factors
The inability of transmitting low-frequency signals without modulators
High-frequency signals are typically transmitted via digital isolators. When sending low-frequency signals, they need modulators. As a result, digital isolators are only appropriate for a few applications. Capacitive/magnetic digital isolators allow direct transmission of high-frequency signals. Low-frequency data cannot travel through the isolation layer of magnetic/capacitive digital isolators. Hence modulators are employed when the frequency range is between 0 and 100 Kbps. As a result, digital isolators may become more expensive.
Based on Technology, the market is segmented into Capacitive Coupling, Magnetic Coupling, and Giant Magnetoresistive. In 2021, the giant magnetoresistive segment garnered a significant revenue share of the digital isolator market. The growth of this segment is attributed to the fact that digital isolators based on GMR isolation technology have superior sensitivity and accuracy. The GMR isolation technology isolators also have a fast switching speed of up to 150 Mbps and a low propagation delay of 10 to 15 nanoseconds. Furthermore, the materials used to make these isolators extend their shelf life. Hence, the demand for giant magnetoresistive-based digital isolators is increasing.
Based on Vertical, the market is segmented into Industrial, Telecommunications, Automotive, Healthcare, Aerospace & Defense, Energy & Power, and Others. In 2021, the industrial segment acquired the largest revenue share of the digital isolator market. Industrial equipment is one of the most common applications for digital isolators.

Based on Application, the market is segmented into Gate Drivers, DC/DC Converters, Analog to Digital Converters, USB & Other Communication Ports, and CAN Isolation & Others. In 2021, the USB & other communication ports segment recorded a significant revenue share of the digital isolator market. The growth of this segment is owing to the increasing deployment of digital isolators in USB along with other communication ports as it ensures the security of the communication interface between the host, like computer, and its peripheral.
Insulating Material Outlook
Based on Insulating Material, the market is segmented into Silicon Dioxide (Sio2)-based, Polyimide-based, and Others. In 2021, the silicon dioxide (Sio2)-based segment procured the largest revenue share of the digital isolator market. The increasing growth of the segment is owing to the increasing utilization of silicon dioxide by major market players. Key firms use silicon dioxide (SiO2)-based insulating material in the production of digital isolators.
Based on Channel, the market is segmented into 4 Channel, 6 Channel, 2 Channel, and 8 Channel & Others. In 2021, the 6-channel segment registered a substantial revenue share of the digital isolators. A 6-channels can have a clock rate of up to 100MHz and a data throughput of 200Mbps. The 6-signal channels have been specifically tuned for SPI, with very short propagation delays of 10ns on the SDI, SDO, and SCLK specified channels and 2ns maximum pulse-width distortion. The IC meets IEC 60747-5-5 requirements and hence, the growth of the segment is being propelled.
Data rate Outlook
Based on Data rate, the market is segmented into More than 75 Mbps, 25 – 75 Mbps, and Up To 25 Mbps. By 2021, the more than 75 Mbps segment procured the highest revenue share of the digital isolator market.
