ROHM Introduces Innovative 100V MOSFET for AI Servers
ROHM Co., Ltd. has made significant strides in the power electronics sector with the launch of their latest 100V power MOSFET, designated RS7P200BM. This MOSFET is specifically designed to provide industry-leading safe operating area (SOA) performance, perfect for hot-swap circuits in AI servers utilizing 48V power supplies, as well as for various industrial equipment that demands robust battery protection.
Addressing the Needs of Modern AI Infrastructure
The rapid advancements in AI technology have heightened the need for servers that can operate reliably while maximizing power efficiency, particularly for those systems that support generative AI and high-performance GPUs. These servers require power MOSFETs that not only manage inrush current but also effectively handle overload conditions, promoting stable functionality. The ongoing shift towards 48V power supplies is driven by their superior energy efficiency, making it essential to design high-voltage, high-efficiency power supply circuits.
The Importance of the RS7P200BM
In response to market demands, ROHM has expanded its portfolio of 100V power MOSFETs suitable for AI server hot-swap circuits. The RS7P200BM is built in a compact DFN5060-8S package, which facilitates a higher density of component placement compared to the previously released RY7P250BM in a DFN8080-8S package, launched in May 2025. This compact design is crucial for optimizing space within server systems.
Outstanding Performance and Efficiency
This new MOSFET boasts an impressively low on-resistance (RDS(on)) of just 4.0 milliohm, measured under conditions of VGS=10V and ID=50A at a temperature of 25°C. Its wide SOA ratings are exceptional: 7.5A at a pulse width of 10ms and 25A at 1ms when operating under VDS=48V. This careful balance between low on-resistance and substantial SOA performance is vital, as it reduces heat generation while in operation. This characteristic not only enhances the efficiency of power supplies but concurrently diminishes the cooling loads and lowers electricity expenses.
Applications in Diverse Industries
ROHM is committed to broadening its range of power devices tailored for 48V systems, significantly contributing to reduced power losses and cooling requirements in data centers. The applications for this innovative MOSFET are extensive and include:
- AI servers and data centers utilizing 48V system power hot-swap circuits.
- Industrial equipment power supplies like forklifts, power tools, and robots.
- Battery-powered equipment, such as automated guided vehicles (AGVs).
- Uninterruptible power supplies (UPS) and emergency power solutions.
