Global AC Surge Protection Device Market, valued at USD 1,149 million in 2024, demonstrates steady expansion with projections reaching USD 1,668 million by 2032. This growth trajectory, representing a compound annual growth rate (CAGR) of 5.7%, is detailed in a comprehensive new report published by Semiconductor Insight. The study underscores the critical importance of surge protection devices in safeguarding electrical systems against voltage spikes, lightning strikes, and transient overvoltages across residential, commercial, and industrial applications.

AC Surge Protection Devices (SPDs) have become indispensable components in modern electrical infrastructure, protecting sensitive equipment from damage and ensuring operational continuity. Their role has expanded significantly with increasing electrification, digitalization, and the growing complexity of power networks. These devices act as the first line of defense, diverting excess voltage away from connected equipment and preventing catastrophic failures in everything from household appliances to industrial machinery.

Digital Infrastructure Expansion: The Primary Growth Catalyst

The report identifies the massive global expansion of digital infrastructure as the paramount driver for SPD demand. The relentless growth of data centers, telecommunications networks, and smart grid implementations creates unprecedented need for robust electrical protection solutions. With the global data center market projected to exceed $400 billion annually, the correlation between digital infrastructure investment and surge protection demand is direct and substantial.

"The concentration of critical infrastructure projects in the Asia-Pacific region, which accounts for approximately 65% of global SPD consumption, represents a key factor in market dynamics," the report states. With global investments in smart city initiatives and 5G infrastructure exceeding $800 billion through 2030, the demand for advanced surge protection solutions continues to intensify. The transition to IoT-enabled devices and Industry 4.0 technologies further amplifies this need, as these systems require protection tolerances within ±1% of rated voltage.
