Global Digital Isolators market was valued at US$ 447.12 million in 2023 and is anticipated to reach US$ 879.40 million by 2030, witnessing a CAGR of 10.04% during the forecast period 2024-2030.
Digital isolators are electronic devices that are used to transfer digital signals across an isolation barrier while preventing the passage of noise, DC currents, transients, and other electrical interference.
Digital isolators typically use optocouplers, capacitive couplers, or magnetic couplers to transfer the digital signal across the isolation barrier. They are commonly used in applications where electrical isolation is required, such as in industrial control systems, automotive electronics, and medical equipment.
