ROHM Co., Ltd. has introduced the RS7P200BM, a 100V power MOSFET designed to deliver industry-leading safe operating area (SOA) performance in a compact 5060-size (5.0mm × 6.0mm) package. Targeted at hot-swap circuits in AI servers and industrial equipment, this new MOSFET is optimized for 48V power supplies, offering enhanced protection and efficiency for high-demand applications.
The move addresses the growing need for stable and efficient power in servers running generative AI workloads and high-performance GPUs. As AI server power densities rise, hot-swap circuits require MOSFETs capable of safely handling inrush current and overload conditions, ensuring uninterrupted operation while protecting batteries and downstream circuitry.
Compact Package, Higher-Density Mounting
The RS7P200BM uses ROHM’s DFN5060-8S package, smaller than the DFN8080-8S used in the RY7P250BM released in May 2025. The reduced footprint allows higher-density mounting, which is crucial for data centers and AI servers where space is at a premium.
Despite its smaller package, the MOSFET achieves low on-resistance of 4.0 milliohm (VGS=10V, ID=50A, Ta=25°C) while maintaining a wide SOA: 7.5A at a 10ms pulse width and 25A at 1ms under VDS=48V. This combination reduces heat generation, improving overall power supply efficiency, lowering cooling requirements, and reducing operational electricity costs.
Optimized for 48V Server Power
Data centers are increasingly transitioning to 48V power supplies due to their superior conversion efficiency, which helps reduce energy consumption in high-performance AI workloads. ROHM’s RS7P200BM strengthens its 100V MOSFET lineup to support this trend, enabling more high-voltage, high-efficiency power supply circuits for both AI servers and industrial applications.
By balancing low RDS(on) and wide SOA, ROHM’s latest MOSFET addresses a trade-off that has historically limited performance in hot-swap and high-current applications. The result is enhanced reliability, improved thermal management, and better energy efficiency—key factors for modern data centers and AI server infrastructures.
Looking Ahead
ROHM plans to continue expanding its power device portfolio for 48V systems, further reducing power loss and cooling loads while improving server reliability. With generative AI workloads and GPU-intensive computing on the rise, components like the RS7P200BM are positioned to play a critical role in efficient, high-density server power management.
