ROHM Semiconductor has released a new 100V power MOSFET called RS7P200BM, designed for use in AI servers as well as industrial power supplies. This compact device comes in a 5.0mm x 6.0mm package, making it a significant choice for hot-swap circuits in AI servers that use 48V power supplies, as well as for battery protection in industrial applications.
With the rapid growth of AI technology, particularly generative AI and high-performance GPUs, there is an increasing demand for stable and efficient power management in servers. Hot-swap circuits, which allow for components to be replaced without shutting down the system, require MOSFETs that can manage sudden power surges as well as overloads, ensuring stable operation. The transition to 48V power supplies is a significant trend because they offer better energy efficiency in power conversion. The new RS7P200BM MOSFET helps meet this demand by offering both performance and energy efficiency.
The RS7P200BM MOSFET features a low on-resistance of 4.0 mΩ, which allows it to manage high-current conditions efficiently. Its broad Safe Operating Area (SOA) ensures that it can withstand power raises without overheating, enabling to enhanced power supply efficiency in servers. This not only lowers the requirement for cooling but also caters to lower electricity costs.
Mass production of the new MOSFET began in September 2025, and it is now available for purchase through online distributors like DigiKey and Mouser. ROHM is committed to expanding its lineup of 48V power supply solutions, supporting the growing needs of the AI as well as data center markets.
