Alpha and Omega Semiconductor Enables 48V Hot Swap in AI Servers with New High SOA MOSFET in LFPAK 8×8
3 December 2025 Alpha and Omega Semiconductor , a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs, and modules,has announced its AOLV66935 a 100V High Safe Operating Area (SOA) MOSFET in an LFPAK 8×8 package.
AOS says its latest MOSFET is designed as an ideal solution for 48V Hot Swap architectures in AI servers. The power demands of AI servers are intensifying, primarily driven by the increasing performance in the GPU/TPU. In addition to its wide SOA capability, the AOLV66935 Hot Swap MOSFET features very low on-resistance to meet these performance, efficiency and reliability challenges.
The AOLV66935 utilises AOS’ 100V AlphaSGT proprietary MOSFET technology that combines the advantages of trench technology for low on-resistance with high SOA capability. AOS has tested and characterised the SOA at 25°C as well at higher operating conditions of 125°C giving system architects the confidence that the device will operate reliably under harsh conditions. Available in AOS’ state-of-the-art packaging, the MOSFET’s LFPAK 8×8 gull-wing constructed package is 60% smaller compared to the TO-263 (D2PAK) package. It also features advanced clip technology with a high current rating to provide high inrush current capabilities. In addition, the copper clip and packaging technology used offers low thermal resistance for improved thermal management. The AOLV66935 is manufactured in IATF 16949-certified facilities, and its LFPAK 8×8 packaging is compatible with automated optical inspection (AOI) manufacturing requirements.
