ROHM has released the RY7P250BM, a 100V power MOSFET, into the market. It is made for hot-swap circuits in 48V power systems, which are used in industrial power supplies that require battery protection as well as AI servers.
Data centers are dealing with previously unprecedented processing demands as AI technology develops quickly, and server power consumption keeps rising yearly. Specifically, the necessity to both increase power efficiency and enable greater currents has arisen due to the increased use of generative AI and high-performance GPUs.
The industry is switching from 12V systems to more effective 48V power topologies in order to overcome these issues. Additionally, MOSFETs with a broad SOA (Safe Operating Area) and low ON-resistance are needed in hot-swap circuits, which are used to safely switch out modules while servers are still powered on. This protects against overloads and inrush current.
These critical characteristics are provided by the RY7P250BM in a compact 8080-sized package, which helps to improve overall server dependability and energy efficiency while lowering power loss and cooling needs in data centers.
The new product offers a drop-in replacement for current designs as the need for 8080-size MOSFETs increases.
The RY7P250BM is notable for achieving wide SOA (VDS=48V, Pw=1ms/10ms), which is perfect for hot-swap operation. With a low ON-resistance of 1.86m? (VGS=10V, ID=50A, Tj=25°C), which is industry-leading and around 18% lower than the average 2.28m? of existing wide SOA 100V MOSFETs in the same size, power loss and heat generation are also reduced.
In hot-swap circuits, particularly those in AI servers that encounter high inrush currents, wide SOA tolerance is crucial. With 16A at 10ms and 50A at 1ms, the RY7P250BM satisfies this requirement and supports high-load scenarios that traditional MOSFETs find difficult to manage.
Leading worldwide cloud platform provider has also validated ROHM’s new product as a preferred component, and it is anticipated that next-generation AI servers would widely use it. Wide SOA and low RDS(on) have been highly assessed for cloud architecture, particularly in server applications where energy efficiency and dependability are mission-critical.
In order to support the creation of sustainable ICT infrastructure and increased energy savings through high-efficiency, high-reliability products, ROHM will keep adding 48V-compatible power solutions for servers and industrial equipment to its lineup.
