The global digital isolator market size is estimated to be USD 1.8 billion in 2022 and projected to reach USD 2.7 billion by 2027, at a CAGR of 8.3% during the forecast period. Digital isolators are emerging as substitutes for optocouplers which is fuelling the market growth. Further, due to noise-free electronic properties electrical and electronic devices are gaining traction as compared to conventional isolation technology. Digital isolators for gate drivers are increasingly preferred for industrial motor drives. These factors will drive market growth throughout the forecast period.
“Based on the technology, capacitive coupling to account for the largest share during 2022–2027.”
The capacitive coupling segment is estimated to account for the largest market size in 2022. Capacitive coupling offers high efficiency in terms of the size of digital isolators and energy transfer. It is immune to magnetic noises and supports high-speed data transmissions. However, using an electric field for signal transmission increases signal distortion when an external electric field is applied. This may result in issues in high-voltage transmission lines. Modern capacitive-isolated digital input receivers can also help simplify designs of systems wherein digital isolators are to be used. Compared to optocouplers and other systems, these contemporary designs have advantages, including low power dissipation, small boards and modules, simplified system designs, and high-speed operations. Industrial and healthcare verticals can benefit from digital isolators based on capacitive coupling since they use low power and enable simple protection of systems as opposed to electrostatic discharge (ESD) and other electrical surges. Isolators based on capacitor coupling isolation technology are available at comparatively low prices, making it one of the key reasons for the large segment size. Isolators based on capacitor coupling isolation type are available at comparatively low prices in the market. These are the key reasons for the largest size of the capacitive coupling segment of the market.
“CAN Isolation Application to register highest growth rate during the forecast period.”
The controller area network (CAN) isolation segment is estimated to grow at the highest rate during the forecast period. The increase in the use of CAN bus in electric and hybrid electric vehicles, has fueled the application of digital isolators for providing galvanic isolation in CAN buses. CAN is generally used in the automotive and aerospace industries, primarily for automation applications. CAN bus is an International Standardization Organization (ISO)-defined serial communication bus, originally developed for the automotive industry to replace the complex wiring harnesses with a two-wire bus. It protects devices from overvoltage transients between the CAN bus cable network and the systems connected to it. CAN bus is used in electric and hybrid electric vehicles wherein the galvanic isolation barrier is critical between high- and low-voltage parts, therefore digital isolators are being used to provide CAN isolation. Texas Instruments, Broadcom, and Silicon Labs are key players that offer digital isolators for CAN isolation. For instance, Texas Instruments offers an ISO1042-Q1 device, an automotive isolated CAN transceiver with 70 V bus fault protection, and a flexible data rate.
“The industry vertical likely to dominate the digital isolator market from 2022 to 2027”
