As AI technology rapidly advances, data centres are facing unprecedented processing demands and server power consumption continues to increase annually.
In particular, the growing use of generative AI (GenAI) and high-performance GPUs has created a need to simultaneously improve power efficiency while supporting higher currents.
To address these issues, the industry is shifting from 12V systems to more efficient 48V power architectures. Moreover, 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 crucial characteristics in a compact 8080-size package, helping 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.
Significantly, the RY7P250BM achieves wide SOA (VDS=48V, Pw=1ms/10ms) ideal for hot-swap operation. Power loss and heat generation are also minimised with a low ON-resistance of 1.86mΩ (VGS=10V, ID=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, allowing support for high-load conditions conventional MOSFETs struggle to handle.
ROHM’s new product has also been certified as a recommended component by a global Cloud platform provider, where it is anticipated 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 RDS(on) has been highly evaluated for Cloud infrastructure.
Looking ahead, 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.
