In particular, the increasing use of generative AI and high-performance GPUs has created a need to simultaneously improve energy efficiency and support higher currents. To address these challenges, the industry is moving from 12V systems to more efficient 48V power architectures. Furthermore, hot-swap circuits used to safely replace modules while servers remain powered on require MOSFETs that offer both a wide SOA (safe operating area) and low ON-state resistance to protect against inrush currents and overloads.
The RY7P250BM offers these critical features in a compact 8080-sized package, helping to reduce power loss and cooling requirements in data centers while improving overall server reliability and energy efficiency. As demand for 8080-sized MOSFETs grows, this new product provides a direct replacement for existing designs. Notably, the RY7P250BM achieves a wide SOA (VDS=48 V, Pw=1 ms/10 ms), ideal for hot-swap operations. Power loss and heat generation are also minimized with an industry-leading ON resistance of 1.86 mΩ (VGS=10 V, ID=50 A, Tj=25 °C), approximately 18% lower than the 2.28 mΩ typical of existing 100 V MOSFETs with wide SOA of the same size.
High SOA tolerance is essential in hot-swap circuits, especially in AI servers that experience large inrush currents. The RY7P250BM meets this demand, achieving 16 A at 10 ms and 50 A at 1 ms, enabling it to withstand high-load conditions that conventional MOSFETs struggle to handle.
ROHM's new product has also been certified as a recommended component by a leading global cloud platform provider, where it is expected to see widespread adoption in next-generation AI servers. Particularly in server applications, where reliability and energy efficiency are critical, the combination of broad SOA and low RDS(on) has been highly valued for cloud infrastructure.
In the future, ROHM will continue to expand its range of 48V compatible power solutions for servers and industrial equipment, contributing to the development of a sustainable ICT infrastructure and greater energy savings thanks to highly efficient and reliable products.
