Wolfspeed, Inc. introduced its TOLT (TO-Leaded, Top-Side Cooled) package portfolio designed to deliver maximum power density for datacenter rack power supplies. By releasing heat from the top of the package, TOLT significantly improves cooling efficiency, enabling smaller, more reliable power systems that meet the rising demands of AI datacenters.
“AI is pushing datacenter OEMs to be incredibly strategic about the size and total efficiency of their power systems,” said Guy Moxey, vice president of Wolfspeed’s Industrial & Energy business. “Our TOLT product family offers a straightforward path to delivering higher-density, thermally optimized power systems capable of sustaining the demands of AI datacenters, and Wolfspeed’s Gen 4 technology helps these systems run cooler, more efficiently, and more reliably.”
Silicon carbide continues to outpace silicon in high-power applications, supporting gains in performance and system cost across AI datacenters, e-mobility, renewable energy, and battery energy storage. Wolfspeed’s U.S.-based silicon carbide substrate production underpins supply chain resilience and provides a stable domestic source for mission-critical power systems as large AI projects scale.
The initial 650 V TOLT products are available in multiple RDS(on) options, with additional details on Wolfspeed’s third top-side-cooled portfolio to follow in the second half of 2026.
