Siemens and Infineon announce SENTRON 3QD2 modules with silicon carbide technology - Inspenet

Siemens and Infineon have announced a collaboration to introduce SENTRON 3QD2 modules incorporating silicon carbide (SiC) technology, aimed at enhancing energy efficiency and safety in critical indust... Read original →

The Siemens-Infineon alliance on CoolSiC-based SENTRON 3QD2 modules signals a pivotal shift from electromechanical to solid-state protection in industrial power systems. Technologically, this accelerates IGBT obsolescence and forces redesign of power distribution standards in AI data centers and DC microgrids. Regulatory-wise, the solution aligns with EU Green Deal mandates on material efficiency, mitigating carbon border adjustment risks. Competitors like ABB and Schneider will likely fast-track SiC breaker development or acquire U.S. startups (e.g., Atom Power) to close the microsecond-response gap. Within 18 months, such ultrafast protection will become a de facto requirement in hyperscaler procurement specs, spurring advanced packaging investments in Taiwan, China and Southeast Asia—though tighter German-U.S. export controls on wide-bandgap semiconductor tools could constrain supply chain diversification.
