12 Best Performing Semiconductor Stocks to Invest In

10. Power Integrations Inc. (NASDAQ:POWI)

6-Month Performance: 78.21%

Power Integrations Inc. (NASDAQ:POWI) is one of the best performing semiconductor stocks to invest in. On June 1, Power Integrations released ultra-slim, 15 W and 35 W auxiliary power supply reference designs optimized for the NVIDIA Kyber 800 VDC AI data center architecture. By using 1700 V-rated PowiGaN technology, these compact solutions reduce board space and bill of materials by 30 percent while maintaining at least 88 percent efficiency.

These designs integrate InnoMux-2 ICs to provide reliable power for internal data center components, such as gate drivers and MCUs. The use of single-HEMT 1700 V GaN technology allows for a highly efficient, space-saving alternative to bulky, discrete silicon carbide solutions, ensuring wide safety margins on 800 V buses.

By streamlining the design of liquid-cooled blade-rack systems, these reference modules simplify the development of high-density AI infrastructure. The technology provides engineers with a more reliable, efficient foundation for managing critical control functions within demanding, high-voltage data center environments.

Power Integrations Inc. (NASDAQ:POWI) provides analog and mixed-signal semiconductor solutions to original equipment manufacturers and distributors.
