MOSFET ensures reliable AI server power
A 100-V, 200-A MOSFET from Rohm, the RS7P200BM achieves a wide safe operating area (SOA) in a compact DFN5060-8S (5×6-mm) package. The device safely handles inrush current and overload conditions, ensuring stable operation in hot-swap circuits for AI servers using 48-V power supplies.
The RS7P200BM features RDS(on) of 4.0 mΩ (VGS = 10 V, Ta = 25 °C) while maintaining a wide SOA—7.5 A for a 10‑ms pulse width and 25 A for 1 ms at VDS = 48 V. This combination of low on-resistance and wide SOA, typically a trade-off, helps suppress heat generation. As a result, server power supply efficiency improves, while cooling requirements and overall electricity costs are reduced.
Housed in a DFN5060-8S package, the RS7P200BM enables higher-density mounting than the previous DFN8080-8S design. It is now available in production quantities through online distributors including DigiKey and Mouser.
