Is your AI server’s power architecture ready for the demands of modern GPUs and TPUs? The relentless pursuit of performance in artificial intelligence is pushing power requirements to the limit. Alpha and Omega Semiconductor (AOS) is stepping up to the challenge with its new AOLV66935 MOSFET, designed specifically for 48V hot swap applications in AI servers.
This innovative MOSFET promises to deliver a cost-effective, high-performance, and reliable hot swap solution, ensuring your AI infrastructure remains robust and efficient.
## Tackling the Heat: High SOA and Low On-Resistance
The AOLV66935 leverages AOS’s proprietary 100V AlphaSGT™ technology, which combines the low on-resistance of trench technology with a high Safe Operating Area (SOA). This is crucial for hot swap applications where devices need to handle potentially large inrush currents without compromising reliability. AOS has rigorously tested and characterized the SOA at both 25°C and 125°C, giving system architects confidence in its performance under harsh operating conditions.
Furthermore, the device boasts an exceptionally low on-resistance of just 1.86 milliohms (maximum at Vgs=10V). This minimizes power loss and reduces heat generation, crucial for maintaining efficiency and preventing thermal runaway in densely packed AI server environments.
## Compact and Robust Packaging
Space is always at a premium in server design. The AOLV66935 is packaged in AOS’s state-of-the-art LFPAK 8×8, which is 60% smaller than the traditional TO-263 (D2PAK) package. This compact form factor allows for greater design flexibility and higher density deployments. The LFPAK 8×8 also incorporates advanced clip technology with a high current rating, ensuring it can handle the inrush currents associated with hot swapping. Improved thermal management comes from low thermal resistance thanks to the copper clip and packaging technology.
The device is manufactured in IATF 16949-certified facilities and its LFPAK 8×8 packaging is compatible with automated optical inspection (AOI) manufacturing requirements.
## Enabling Reliable 48V Hot Swap
“To be able to perform the 48V hot swap in AI servers requires a MOSFET that excels in high current capability while providing exceptional high SOA robustness and reliability,” said Peter H. Wilson, Sr. Director of MOSFET product line at AOS. The AOLV66935 appears well-positioned to meet these demands, providing a crucial building block for the next generation of AI infrastructure. Available now, it’s priced at $3.6 in 1,000-piece quantities.
