Infineon Launches 400V Silicon Carbide MOSFETs to Boost AI Server Power Efficiency
Infineon Unveils Next-Generation CoolSiC MOSFETs for Enhanced Power Density and Efficiency in AI Server PSUs
BonChip Electronics, a leading distributor of Infineon Technologies products, is excited to announce the availability of the innovative CoolSiC™ MOSFET 400 V family. This groundbreaking series addresses the ever-increasing power demands of Artificial Intelligence (AI) processors, enabling server power supplies (PSUs) to deliver exceptional performance within space constraints.
Optimizing Power Delivery for Demanding AI Applications
The surge in energy consumption by high-performance GPUs, projected to reach 2 kW or more per chip by 2030, necessitates advancements in server PSU technology. Infineon's CoolSiC MOSFET 400 V family tackles this challenge head-on, offering:
- Reduced Size and Enhanced Power Density: These MOSFETs are specifically designed for the AC/DC stage of AI server PSUs, complementing Infineon's comprehensive PSU roadmap. Their compact size allows for high power density (over 100 W/in³) in a multi-level PFC configuration, ideal for space-constrained server environments.
- Unmatched Efficiency: The CoolSiC MOSFET 400 V family boasts ultra-low conduction and switching losses compared to existing 650 V SiC and Si MOSFETs. This translates to a significant efficiency improvement (up to 0.3 percentage points) in AI server PSUs compared to solutions using 650 V SiC MOSFETs.
- Broader Application Suitability: Beyond AI server PSUs, these versatile MOSFETs excel in various applications, including solar and energy storage systems (ESS), inverter motor control, industrial and auxiliary power supplies (SMPS), and even solid-state circuit breakers for residential buildings.
Richard Kuncic, Head of the Power Systems Business Line at Infineon, emphasizes the company's commitment to innovation: "Infineon offers a comprehensive portfolio of high-performance MOSFETs and GaN transistors to meet the stringent design and space requirements of AI server PSUs. The CoolSiC MOSFETs 400 V G2 represent our unwavering dedication to empowering customers with advanced products that drive superior energy efficiency in cutting-edge AI applications."
Unparalleled Performance and Reliability
The CoolSiC MOSFET 400 V family delivers exceptional performance and reliability:
- Superior Efficiency: When combined with CoolGaN transistors in the DC/DC stage, these MOSFETs enable AI server PSUs to deliver over 8 kW of power with a power density increase exceeding 3x compared to existing solutions.
- Diverse Product Portfolio: The family encompasses ten products featuring five R DS(on) classes (ranging from 11 to 45 mΩ) available in Kelvin-source TOLL and D²PAK-7 packages with .XT interconnect technology.
- Robustness and Reliability: These MOSFETs boast a 400 V drain-source breakdown voltage (at Tj = 25 °C), making them ideal for 2- and 3-level converters and synchronous rectification. Additionally, they are 100% avalanche-tested and engineered to withstand harsh switching conditions.
- Advanced Thermal Management: The combination of Infineon's highly robust CoolSiC technology and the .XT interconnect technology empowers these devices to handle power surges and transients caused by fluctuations in AI processor power demands.
- Exceptional Performance at High Temperatures: Both the .XT connection technology and a low and positive R DS(on) temperature coefficient contribute to outstanding performance even at elevated junction temperatures.
