Global Isolation IC Supply, Demand and Key Producers, 2026-2032

The global Isolation IC market size is expected to reach $ 7212 million by 2032, rising at a market growth of 8.1% CAGR during the forecast period (2026-2032).

Isolation IC refers to a chip with electrical isolation characteristics between the chip input and output. The purpose of electrical isolation includes high and low voltage circuit insulation, noise isolation, matching level, etc. In high-voltage systems or multi-circuit connection systems, isolation chips are required due to safety regulations or electrical isolation requirements.

In 2025, global sales of isolator chips reached 2,717 million units, with an average selling price of US$1,492 per k units. Total production capacity was approximately 3,179 million units, and the industry's average gross profit margin was approximately 43.50%. The industry chain consists mainly of upstream raw materials such as wafers and packaging materials, while downstream applications include industrial, automotive, telecommunications, and energy sectors.

The global Isolation IC market is highly fragmented with numerous manufacturers. In 2025, the top five vendors—ADI, Texas Instruments, Infineon, Skyworks, and Onsemi—collectively held approximately 58% of the market share. The Asia-Pacific region is the largest Isolation IC market globally, with a market share of approximately 54%, followed by North America and Europe with 24% and 17% respectively. From a technological perspective, capacitively coupled isolation architectures based on CMOS processes have become mainstream. Manufacturers continue to optimize common-mode transient immunity (CMTI), transmission consistency, and temperature characteristics to meet reliability requirements in extreme environments. Meanwhile, integration is a significant trend, with multi-channel, high-integration, and on-chip diagnostics becoming standard features, helping customers simplify system design and shorten development cycles. In terms of product types, Isolation IC mainly include digital isolators, isolation interfaces, isolated drivers, isolation amplifiers, and others. Isolated drivers have been dominant for the past few years, holding approximately 48% of the market share in 2025. In terms of applications, industry is currently the largest consumer market for Isolation IC, accounting for approximately 44% of revenue in 2025, followed by automotive, with a share of approximately 20%.
