Semiconductor specialist ROHM has strengthened its high-efficiency and high-reliability power solutions for AI servers and industrial equipment.


ROHM recently introduced the new 'RS7P200BM' compact, high-voltage power MOSFET optimized for power supplies.

This product adopts the DFN5060-8S package measuring 5.0 mm x 6.0 mm, enabling high-density mounting, and realizes the industry's highest SOA (Safe Operating Area) tolerance, making it suitable for hot-swap circuits and battery protection circuits.

The RS7P200BM corresponds to the hot-swap circuit of AI servers using 48V system power, and has a high SOA tolerance of 7.5A at a pulse width of 10ms and 25A at 1ms under VDS=48V conditions. This enables stable operation even in inrush current or overload situations, thereby improving both server reliability and power efficiency.

In addition, the ON resistance (RDS(on)) is designed to be low at 4.0 mΩ (VGS=10 V, ID=50 A, Ta=25 °C), which suppresses heat generation during power supply and reduces cooling load, contributing to power cost savings.

This new product adopts a 5060-size, significantly smaller than the "RY7P250BM" in the DFN8080-8S package released in May 2025, enabling high-density mounting. This design takes into account the space constraints of AI servers and data centers, enhancing system design flexibility and efficiency.

In addition to AI servers, the RS7P200BM can also be widely used in 48V system industrial equipment power supplies such as forklifts, power tools, robots, and fan motors, as well as battery-based equipment such as AGVs (automated guided vehicles), UPSs, and emergency power systems.

The sample price is 800 yen (excluding tax) per unit, and can be purchased from major online parts distribution sites such as Chip 1 Stop and CoreStaff Online.
