Automotive GaN Devices Market Segmentation:

Automotive GaN Devices Market  Segmentation By Device Type:

  • Opto-Semiconductors
  • Power Semiconductors
  • RF Semiconductors

In the Automotive Gallium Nitride (GaN) Devices Market, opto-semiconductors have traditionally ruled, accounting for about 39.1% of the market share in 2024, mainly because of their wide application base in lighting and display systems. However, the segment of power semiconductors is growing at the highest rate. This is owing to the accelerating deployment of electric vehicles (EVs) and the need for effective power management solutions. On the other hand, RF semiconductors are still a dominant part of automotive radar and communications systems, helping immensely in overall market growth.
