Santa Clara, CA and Kyoto, Japan, July 01, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced the launch of the RY7P250BM, a 100V power MOSFET optimized for hot-swap circuits in 48V power systems used in AI servers and industrial power supplies that require robust battery protection.

As AI technology rapidly advances, data centers are facing unprecedented processing demands and server power consumption continues to increase annually. In particular, the growing use of generative AI and high-performance GPUs has created a need to simultaneously improve power efficiency while supporting higher currents. To address these challenges, the industry is shifting from 12V systems to more efficient 48V power architectures. Furthermore, in hot-swap circuits used to safely replace modules while servers remain powered on, MOSFETs are required that offer both wide SOA (Safe Operating Area) and low ON-resistance to protect against inrush current and overloads.

The RY7P250BM delivers these critical characteristics in a compact 8080-size package, helping to reduce power loss and cooling requirements in data centers while improving overall server reliability and energy efficiency. As the demand for 8080-size MOSFETs grows, this new product provides a drop-in replacement for existing designs. Notably, the RY7P250BM achieves wide SOA (V_DS=48V, Pw=1ms/10ms) ideal for hot-swap operation. Power loss and heat generation are also minimized with an industry-leading low ON-resistance of 1.86mΩ (V_GS=10V, I_D=50A, Tj=25°C), approximately 18% lower than the typical 2.28mΩ of existing wide SOA 100V MOSFETs in the same size.

Wide SOA tolerance is essential in hot-swap circuits, especially those in AI servers that experience large inrush currents. The RY7P250BM meets this demand, achieving 16A at 10ms and 50A at 1ms, enabling support for high-load conditions 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 gain widespread adoption in next-generation AI servers. Especially in server applications where reliability and energy efficiency are mission-critical, the combination of wide SOA and low R_DS(on) has been highly evaluated for cloud infrastructure.

Going forward, ROHM will continue to expand its lineup of 48V-compatible power solutions for servers and industrial equipment, contributing to the development of sustainable ICT infrastructure and greater energy savings through high-efficiency, high-reliability products.
