XIAMEN, ChinaApril 22, 2026 /PRNewswire/ — As the demand for AI computing power surges, data center power supplies are undergoing a generational shift from silicon to silicon carbide (SiC). In this race for energy efficiency, SiC devices produced by Sanan Optoelectronics’ Hunan base have been batch-applied in Vertiv’s power systems, quietly becoming the “invisible heart” supporting global AI infrastructure.
Vertiv is the absolute leader in global data center infrastructure and the exclusive partner for NVIDIA’s liquid cooling solutions, renowned in the industry for its stringent quality standards. In the fourth quarter of 2025, Vertiv’s order volume increased by 252% year-over-year, with a backlog reaching $9.5 billion.
Sanan Optoelectronics precisely meets Vertiv’s rigorous standards with its SiC chips’ low conduction loss, high switching frequency, and excellent high-temperature stability. As of the first quarter of 2026, Sanan has cumulatively supplied over 5 million SiC chips to Vertiv; the annual supply volume in 2025 grew by 80% compared to the previous year, and increased by another 123% year-over-year in the first quarter of 2026. In early 2026, Vertiv awarded Sanan Optoelectronics the “Outstanding Contribution Award.” Vertiv’s supply chain head stated, “Sanan’s SiC devices have taken our power module efficiency to the next level.”
The collaboration extends far beyond supply. For Vertiv’s high-density data center power supply solutions, Sanan Optoelectronics participated in thermal simulation and device selection. By optimizing switching characteristics, it helped the customer achieve power module efficiency exceeding 98% and simplified the thermal structure. The next step involves a joint plan to establish a next-generation high-voltage power supply laboratory, focusing on the innovative application of 3300V SiC MOSFETs in data center SST systems. The deep synergy between Sanan Optoelectronics and Vertiv paves a more efficient and reliable “core” path for the global AI computing power chain.
Side by side, making every chip count.
