The global automotive diode market size was valued at USD 10.48 billion in 2022. The market is projected to grow from USD 10.90 billion in 2023 to USD 16.97 billion by 2030, exhibiting a CAGR of 6.53% during the forecast period.

The automotive diode refers to a cylindrical striped component that mandates the current to flow in a single direction. It is an important component in vehicles, as it protects the vehicle equipment from current spikes that damage components and the electrical system of a vehicle.

The market growth can be credited to the increasing complexity of automotive electronics and the rising demand for advanced safety features and energy-efficient technologies in vehicles.

The current trend in the market is the development of advanced silicon carbide-based diodes. In April 2023, Ferrari signed a partnership with Samsung Display to integrate its organic light-emitting diode (OLED) display panel in its cars.

Despite such growth opportunities, factors such as the limited availability of raw materials, such as semiconductor, challenge the market expansion.


Supply Chain Disruptions and Semiconductor Shortage Impacted the Supply of Automotive Diodes Negatively during the Pandemic 

The COVID-19 pandemic abruptly hit the market of automotive diodes. The decline in the production of automobiles due to the restrictions, factory closures, or partial shutdowns led to lower demand for automotive diodes in the market. The pandemic forced many automotive companies to prioritize cost-saving measures and delay or scale back their investments in research and development. In addition, the supply chain constraints caused due to limited availability of raw materials affected the market during the pandemic.

Furthermore, the slowdown in technological advancement impacted the introduction of advanced, innovative automotive systems and components, which especially included specific diodes. However, as the automotive industry recovers and adapts to the new normal, the demand for automotive diodes rebounded, driven by the resurgence of vehicle production, which fuelled the demand for the product in the post-COVID-19 era.


Increasing Adoption of Electric Vehicles to Boost the Market Growth

The automotive industry is witnessing a significant shift toward electric mobility. This transition has led to an increased demand for in-vehicle diodes capable of handling high-voltage applications and supporting the power electronics systems in electric vehicles. Diodes used in electric vehicles need to meet the specific requirements for managing operations, such as providing efficiency, catering to low power losses, and achieving temperature stability in the vehicle. This has compelled major players to focus on the development of diodes suitable for electric vehicles. In November 2022, Nexperia developed 650-volt recovery diodes in compact CFP packaging for electric vehicle onboard chargers, power supplies, and solar inverters.

Thus, along with the growing number of electric vehicles, the rising demand for advanced and specialized diodes for these types of vehicles is expected to drive the market growth over the forecast period.
