Don't hesitate to ask ChatGPT/Claude Which of the companies you asked is more like the real beneficiary of 800V DC/SST 1) Wolfspeed（WOLF） The most authentic. There are already 3.3kV SiC modules available There are already 10kV SiC MOSFETs available Officially, they are directly used in SST and 800V DC AI data center scenarios. (http://(wolfspeed.com)) understand: Wolfspeed is more like a 'core hardware supplier' in this chain. 2) Navitas Semiconductor（NVTS） It is also very strong and leans towards the "800V power supply architecture" application layer. It clearly demonstrated a 20kW 800V to 6V DC-DC power delivery board in Q1 2026 We also collaborated with EPFL to showcase a 250kW SST (solid-state transformer) using 3300V and 1200V SiC devices, with the goal of achieving an 800V DC distribution. ( http://ir. (navitassemi.com)) understand: Navitas is not just a GaN (gallium nitride) company, it is already deepening its high-voltage power supply to AI data centers. 3) Infineon（IFX） Very strong, belonging to the "full spectrum power semiconductor" giant. The official statement states that it has Si/SiC/GaN full spectrum power technology. In 2026, it and DG Matrix will launch SST (Solid State Transformer), specifically targeting AI data centers and industrial power. There is also an official white paper that lists 800V or ± 400V bus as the direction of data center power evolution. (http://(infineon.com)) understand: Infineon is the "most stable beneficiary of large factories", but not as pure as WOLF. 4) STMicroelectronics（STM） There is relevant capability, but on this 800V DC/SST line, the public signal is not as direct as the above three. STM certainly has SiC, power devices, and power management capabilities; But if you ask 'who is the most explicit bet on AI data center 800V DC/SST in public materials', STM is currently not at the forefront. These types of companies are more suitable to be seen as beneficiaries of broad-spectrum power semiconductors, rather than being the most focused on SST targets. 5) Enphase（ENPH） There is a concept, but it leans more towards "new directions/options". In April 2026, Enphase officially released the IQ SST (Solid State Transformer), specifically designed for AI data centers and 800V DC power architectures. ( http://investor. (enphase.com)) understand: This indicates that Enphase wants to expand from residential energy storage/inverters to data center power architecture. But it's more like a new attempt than having already delved into this chain like Wolfspeed. Simple sorting: Who is more like '800V DC/SST really benefits' If I only look at the degree of directness in public materials, I would arrange it like this: Wolfspeed（WOLF） Navitas（NVTS） Infineon（IFX） Enphase（ENPH） STMicroelectronics（STM）
