The electrification of automobiles and the rapid integration
of sophisticated electronic systems in modern vehicles are fundamentally
changing how the automotive supply chain functions. Amid this transformation,
the automotive multilayer varistor market has emerged as a critical
segment supporting robust circuit protection in vehicle electronics.
Multilayer varistors (MLVs) are ceramic components designed
to protect automotive electrical circuits against surges, voltage transients,
and electrostatic discharge (ESD). As automotive architecture evolves to
accommodate advanced driver-assistance systems (ADAS), infotainment units,
connectivity modules, electric drivetrains, and sensors, the need for compact,
highly efficient, and durable varistors has intensified.
Automotive Multilayer Varistor Market Outlook 2035
The global industry was valued at US$ 91.1 Mn in 2024.
It is estimated to grow at a CAGR of 7.7% from 2025 to 2035 and reach US$
212.1 Mn by the end of 2035.
This projected growth reflects the expanding application of
multilayer varistors across automotive segments such as powertrains, body
electronics, infotainment, and ADAS. In particular, EVs and connected vehicles
are set to contribute significantly to market expansion over the next decade.

Market Dynamics and Key Growth Drivers
The automotive multilayer varistor market is experiencing a
surge in growth due to multiple factors:
- Rising
Electronics Integration in Vehicles:
Today’s vehicles contain up to 100 electronic control units (ECUs), handling everything from safety features to entertainment systems. These components are susceptible to overvoltage and require robust protection, making varistors indispensable. - Accelerated
EV Adoption:
Electric vehicles (EVs) feature more power electronics than traditional internal combustion engine (ICE) vehicles. From battery management systems to inverter circuits and charging infrastructure, MLVs play a pivotal role in safeguarding sensitive components. - Miniaturization
and Higher Voltage Requirements:
As demand grows for compact automotive designs, varistors are required to be smaller while still offering high energy-handling capabilities and a wide range of operating voltages. - Regulatory
Push for Safety and Reliability:
Compliance with international automotive standards such as AEC-Q200 and ISO 26262 for functional safety is pushing OEMs to use high-quality protection components like multilayer varistors.
