Infineon Technologies and Siemens are working together to advance electrical protection and enhance reliability in data centre operations, production facilities and battery storage systems. As part of the collaboration, Infineon will supply silicon carbide (SiC) power modules to Siemens for use in its SENTRON 3QD2 semiconductor circuit breakers. This is expected to enhance the efficiency, power density and reliability of Siemens’ protection solution.
“AI data centres and factories are becoming increasingly electrified and complex. This increases vulnerability to electrical failures and drives the demand for more sustainable, efficient and reliable power distribution systems,” said Andreas Weisl, executive VP and chief Sales officer of Industrial and Infrastructure at Infineon.
The Siemens SENTRON 3QD2 circuit breaker uses semiconductor components and smart protection algorithms to perform its primary function. This enables ultra-fast interruption in the microsecond range, up to 1000 times faster than conventional systems. This capability is essential for direct current (DC) grids and is said to offer a significant increase in protection and system availability, which is crucial in applications like industrial manufacturing and AI data centres.
“Our new direct current portfolio offers innovative solutions that … enable the development of resilient, future-proof infrastructure,” said Markus Grabmeier, CEO Electrical Products at Siemens Smart Infrastructure. “Direct current applications can decrease energy consumption and substantially cut material usage. By integrating batteries, peak power can also be significantly reduced.”
The collaboration addresses the increasing demands of power‑critical applications, where speed, precision and reliability are essential. Their approach integrates Infineon’s 62 mm CoolSiC MOSFET module 1200 V into Siemens’ advanced protection concepts, with the intention of supporting the growing adoption of DC grids and highly electrified environments.
