The increasing complexity of automotive electronics, rapid vehicle electrification, and rising adoption of advanced driver assistance systems (ADAS) are creating significant demand for reliable protection technologies. MLVs are increasingly used in sensors, electronic control units, lighting systems, infotainment, connectivity systems, and other vehicle electronics.

Market Overview

Automotive multilayer varistors protect electronic circuits from transient overvoltage by absorbing and dissipating excessive electrical energy. Their compact construction makes them particularly suitable for modern vehicles, where electronic components must deliver high performance while occupying minimal space.

The market is being supported by the growing adoption of electric and hybrid vehicles, increasing electronic content per vehicle, stricter safety and reliability requirements, and technological developments in automotive electronics. Electrification is especially important because EVs incorporate sophisticated battery management systems, power electronics, inverters, motors, and energy-recovery systems that require dependable surge protection.

Key Drivers of Market Growth

Growth of Electric and Hybrid Vehicles
The rapid expansion of electric and hybrid vehicles is one of the strongest growth drivers for automotive MLVs. EVs and hybrid vehicles incorporate sophisticated electronic architectures involving battery management systems, electric drivetrains, inverters, charging systems, and energy-recovery circuits.

These systems are vulnerable to transient voltage events, making effective circuit protection increasingly important. In January 2025, global sales of electric and plug-in hybrid vehicles increased 18% year-over-year to approximately 1.3 million units. Europe recorded 21% growth to around 0.25 million units, while China recorded an 11.8% increase to approximately 0.7 million units.

The continued expansion of EV production is therefore expected to directly support demand for automotive-grade MLVs.

Technological Advancements in Automotive Electronics
Automobiles are becoming increasingly dependent on electronic systems. ADAS, infotainment, automotive Ethernet, connectivity, sensors, electronic power steering, and sophisticated control modules all require stable and reliable electrical operation.

MLVs help reduce electrical noise and protect sensitive circuits against voltage irregularities. At the same time, advances in component miniaturization are enabling manufacturers to develop smaller and more efficient varistors suitable for space-constrained automotive applications.

Key Players and Industry Leaders

The competitive landscape includes established electronic-component manufacturers such as AVX Corporation, Panasonic Corporation, Murata Manufacturing, and TDK Corporation. These companies are focusing on high-performance varistors offering improved voltage protection, compact dimensions, reliability, and longer operating life.

Other prominent manufacturers include AEM Components (USA), Amotech, Bourns, Cham How Corporation, MARUWA, Eaton, KEMET, KOA Speer Electronics, KYOCERA AVX Components, Littelfuse, INPAQ Technology, SFI Electronics Technology, Shenzhen Sunlord Electronics, Stackpole Electronics, Thinking Electronic Industrial, Vishay Intertechnology, Walsin Technology, Fenghua Electronics, and others.

Research and development, strategic partnerships, acquisitions, product innovation, and expansion of automotive-grade portfolios remain important competitive strategies.

Key Trends for the Future

One of the major trends is the increasing use of 5V-50V MLVs, which accounted for approximately 32.8% of the market in 2024. These components are widely used in low-voltage automotive electronics, including sensors, infotainment systems, communication networks, and control modules.

The continued integration of ADAS, electronic power steering, connectivity, and automotive Ethernet is expected to further increase demand for compact low-voltage protection components. Automotive manufacturers are also emphasizing smaller packages that can be integrated into increasingly space-constrained electronic assemblies.
