# Infineon and SolarEdge SSCB technology partnership > Live situation record from CLSTR: https://clstr.news/situations/infineon-and-solaredge-sscb-technology-partnership > Updated: 2026-09-21T10:46:17.000Z. Sources: 7. Developments: 2. Infineon and SolarEdge Technologies have expanded their collaboration to develop solid-state circuit breaker (SSCB) technology. This initiative is specifically designed to support 800 VDC power architectures within AI and hyperscale data centers. The partnership addresses engineering difficulties inherent in high-voltage direct-current (DC) distribution. Because DC circuits lack a natural current zero, traditional mechanical breakers are often slow and prone to arcing. The new SSCB solution aims to provide fast fault isolation, interrupting faults within microseconds without the need for mechanical contacts. Under the agreement, SolarEdge leads the design of the SSCB solution, while Infineon provides silicon carbide (SiC) JFET technology to ensure robust protection. This work builds upon an existing partnership involving SolarEdge’s solid-state transformer (SST) platform, which uses Infineon components to facilitate efficient conversion from medium-voltage grids to DC power. ## Timeline ### 2026-09-21: SolarEdge and Infineon partner on solid-state circuit breakers for AI data centers SolarEdge and Infineon are collaborating to develop solid-state circuit breakers for 800 VDC AI data centers to improve efficiency and fault protection in high-voltage DC distribution. 2 sources. https://clstr.news/cluster/solaredge-and-infineon-partner-on-solid-state-circuit-breakers-for-ai-data-centers ### 2026-09-10: Infineon and SolarEdge partner on solid-state circuit breakers Infineon and SolarEdge are collaborating to develop solid-state circuit breakers for 800VDC data centers, aiming to provide microsecond fault isolation for AI and hyperscale infrastructure. 5 sources. https://clstr.news/cluster/infineon-and-solaredge-partner-on-solid-state-circuit-breakers --- Cite as: Infineon and SolarEdge SSCB technology partnership.
