Modern data centers and high-performance server platforms demand ever-higher power density, efficiency and reliability while operating under continuous high-load conditions. Traditional silicon power devices are increasingly constrained by switching losses, thermal limits and system size. Silicon Carbide (SiC) technology addresses these challenges by delivering significantly higher critical electric field strength, superior thermal conductivity and faster switching capability.
Littelfuse offers a complete SiC power portfolio tailored for these demanding applications. The range includes 650 V and 1200 V SiC MOSFETs in both standard discrete packages and advanced ceramic-based isolated packages (ISO247 and top-side-cooled SMPD-B half-bridge configurations), together with matching SiC Schottky diodes, optimized gate drivers and SMFA asymmetrical TVS diodes for precise gate protection.

 

Key advantages for server and data-center power supplies include:

 

-Lower conduction and switching losses that improve overall system efficiency
-Higher power density and reduced cooling requirements
-Stable RDS(on) across temperature for predictable thermal design
-Isolated packages that simplify isolation strategy, reduce EMI and improve thermal performance by up to 50 %
-Single-component asymmetrical gate protection that replaces conventional multi-device solutions and minimizes parasitic effects in high-frequency switching

 

These devices are particularly well suited to LLC resonant converters, PFC stages and high-current DC-DC power supplies commonly used in enterprise servers, AI computing racks and hyperscale data centers.
By combining SiC MOSFETs, Schottky diodes, gate drivers and dedicated protection devices into a cohesive solution, designers can achieve higher efficiency, greater power density and improved long-term reliability while simplifying board layout and thermal management.
