The multilayer varistor (MLV) market is on a growth trajectory driven by the global surge in electronic device manufacturing, rapid expansion of telecommunications infrastructure, and the electrification of transport and energy systems. According to the latest industry insights, the global multilayer varistor market was valued at US$ 0.5 billion in 2024 and is projected to reach US$ 1.1 billion by 2035, expanding at a CAGR of 6.9% from 2025 to 2035.

As industries move toward smarter, more connected, and miniaturized electronic ecosystems, MLVs are emerging as essential components for voltage surge protection and circuit stability.

What Are Multilayer Varistors and Why They Matter

A multilayer varistor is an electronic component designed to protect circuits from voltage spikes and transient surges. Composed of multiple layers of zinc oxide and ceramic materials, these devices exhibit nonlinear voltage-current characteristics that allow them to absorb excess voltage without damaging sensitive components.

In modern applications — from smartphones and EVs to industrial machinery and 5G base stations — MLVs ensure reliable performance, reduce system failures, and extend product lifespans. Their compact design, high reliability, and ability to handle large surge currents make them indispensable in the era of electronic miniaturization and high-performance computing.

Key Market Drivers

1. Rising Demand from the Consumer Electronics Industry

The global boom in consumer electronics — powered by AI-enabled devices, IoT integration, and smart home technologies — is a major catalyst for the MLV market. Governments are also promoting local electronics production, further amplifying demand.

For instance, India’s Ministry of Electronics and Information Technology (MeitY) projects that the country’s electronics market will reach US$ 300 billion by 2025-26. Similarly, Taiwan recorded an 11.2% rise in electronic export orders in 2024 due to increased demand for AI-driven products.

With more smartphones, laptops, and wearables being produced each year, manufacturers are prioritizing reliable circuit protection solutions — and MLVs provide an efficient and cost-effective option. Their ability to handle low-voltage protection (up to 30V) makes them ideal for compact devices with delicate internal components.

2. Expansion of Telecommunications and 5G Infrastructure

The ongoing global rollout of 5G networks is another critical growth driver for the multilayer varistor market. Advanced telecom infrastructure requires continuous connectivity and uninterrupted power supply — both of which rely on effective surge protection systems.

Governments worldwide are investing heavily in telecom infrastructure upgrades. India has committed ₹26,316 crore for 4G expansion projects to connect over 6,200 villages, while Australia’s US$ 3.8 billion NBN upgrade aims to improve fiber networks and ensure reliable domestic communication services.

In both cases, MLVs play a vital role in protecting network hardware, routers, and base stations from voltage surges, thereby maintaining network stability and reducing downtime.

3. Growth of Electric Vehicles and Renewable Energy Systems

The transition toward electric mobility and renewable energy is generating new opportunities for MLVs. Electric vehicles (EVs), charging stations, and solar inverters require robust protection against power fluctuations and electromagnetic interference (EMI).

As global EV adoption accelerates, the integration of varistors in battery management systems, power modules, and charging circuits is becoming increasingly common. Furthermore, renewable energy systems — particularly wind and solar — rely on multilayer varistors to protect grid interfaces and power converters from sudden voltage spikes.

Regional Outlook: East Asia Leading the Charge

East Asia remains the largest and most dynamic market for multilayer varistors, accounting for 38% of the global share in 2024. The region’s dominance stems from its strong electronics manufacturing ecosystem, world-class R&D capabilities, and cost-effective production processes.

Countries such as China, Japan, South Korea, and Taiwan lead in producing both consumer electronics and automotive components — two of the biggest end-use segments for MLVs. Moreover, their continuous investment in miniaturization technologies and semiconductor innovation reinforces the region’s leadership position.

Europe and North America, meanwhile, are witnessing steady growth due to stringent EMC (electromagnetic compatibility) regulations and increased focus on industrial safety standards. These regions are also key markets for high-performance varistors used in aerospace, healthcare, and telecommunication applications.

Key Players and Market Innovations

The global multilayer varistor industry is competitive and innovation-driven. Leading players include TDK Corporation, Panasonic Corporation, Vishay Intertechnology, Bourns, Littelfuse, KYOCERA AVX Components, Eaton Corporation, Amotech Co. Ltd., and KOA Speer Electronics.

Recent product launches reflect a push toward enhanced performance and durability:

• In July 2024, KOA Speer Electronics introduced the NV73S series, a new MLV that can handle surge currents up to 6,000 A — five times more than previous models.
• In January 2024, Bourns, Inc. unveiled its BVR Series, offering superior low-voltage protection for sensitive electronics through improved energy absorption and power dissipation capabilities.

These advancements highlight how the market is evolving to meet growing demands for higher energy tolerance, miniaturization, and cost efficiency.

Future Outlook

The multilayer varistor market is set for a decade of consistent growth, propelled by trends such as IoT expansion, EV adoption, renewable energy integration, and AI-driven electronics manufacturing. As digital transformation accelerates, the importance of surge protection technologies will continue to rise across industries.

By 2035, MLVs will not just be passive components but integral elements enabling the reliability, safety, and longevity of next-generation electronic systems — powering everything from smart cities to autonomous vehicles.
