en.Wedoany.com Reported - Infineon Technologies and Siemens are collaborating to develop semiconductor circuit breaker technology based on silicon carbide for data centers, production equipment, and battery storage systems. The technology utilizes Infineon's silicon carbide power modules to enhance the efficiency, power density, and reliability of Siemens' circuit breakers, with the core product being the semiconductor circuit breaker "Sentron 3QD2."
A semiconductor circuit breaker is a high-speed switching device based on semiconductors that protects electrical components from damage during short circuits or overloads. Andreas Weisl, Executive Vice President and Chief Sales Officer for Industrial and Infrastructure at Infineon, stated that the increasing electrification of AI data centers and factories, along with growing circuit complexity, raises the risk of electrical faults, driving greater market demand for more sustainable, efficient, and reliable power distribution systems.
Unlike traditional electromechanical circuit breakers that rely on mechanical components to interrupt current, the Sentron 3QD2 uses semiconductor components and intelligent protection algorithms for circuit protection. Traditional electromechanical circuit breakers typically operate within a millisecond timeframe, whereas the Sentron 3QD2 achieves ultra-fast shutdown in microseconds—up to 1,000 times faster than conventional systems. This characteristic is crucial for DC networks, significantly improving protection and system availability. In applications such as industrial manufacturing or AI data centers, even minor delays can lead to costly downtime, data loss, or hardware damage.
In this collaboration, Infineon's "62-mm Cool SiC" 1200V MOSFET modules are integrated into Siemens' protection solutions. The two companies aim to provide more resilient and efficient energy infrastructure solutions for critical facilities—especially those requiring high speed, precision, and reliability. A demonstration of the Siemens semiconductor circuit breaker Sentron 3QD2 will be presented at the Infineon booth (Hall 7, Booth 470) at PCIM Europe 2026, held from June 9 to 11, 2026, in Nuremberg.
