As AI technology advances, data centers face increasing power demand driven by generative AI and high-performance GPUs, creating a need to improve efficiency while supporting higher currents. To address these challenges, the industry is shifting from 12V to more efficient 48V power architectures, where hot-swap circuits are used to replace modules without shutdown. These circuits require MOSFETs that provide both a wide Safe Operating Area (SOA) and low ON-resistance to protect against inrush currents and overloads.

The RY7P250BM combines a wide SOA and low ON-resistance in a compact 8080-size package, reducing power loss, heat, and cooling requirements while enhancing server reliability and energy efficiency. As demand for 8080-size MOSFETs grows, it offers a drop-in replacement for existing designs. It achieves a wide SOA (VDS=48V, Pw=1ms/10ms), ideal for hot-swap circuits. Power loss and heat are minimized with an industry-leading* low ON-resistance of 1.86 milliohms (VGS=10V, ID=50A, Tj=25 degrees C), approximately 18% lower than the typical 2.28 milliohms of comparable 100V wide SOA MOSFETs.

A wide SOA is critical for hot-swap circuits in AI servers subject to large inrush currents. The RY7P250BM meets this need with 16A at 10ms and 50A at 1ms, handling high-load conditions beyond conventional MOSFETs.

The RY7P250BM has also been certified as a recommended component by a leading global cloud platform provider and is expected to see broad adoption in next-generation AI servers. Its wide SOA and low RDS(on) are highly evaluated in mission-critical cloud applications.

ROHM will continue to expand its 48V-compatible power solutions for servers and industrial equipment, supporting sustainable ICT infrastructure and energy savings through high-efficiency, high-reliability products.
