A high SOA is essential in server hot swap applications where the MOSFET needs to be robust to manage the high inrush current effectively. The AONS30300 delivers high SOA robustness under 10VDS with 10ms pulse width and has an SOA limit ~48V. This new 30V MOSFET from AOS is available in a compact DFN 5x6 package and has a maximum Rd(son) of 0.58mΩ at an applied Gate-Source Voltage equal to 10VGS. In addition, the AONS30300 is rated at Tj=175°C.

“High reliability is an essential metric in datacenter infrastructure. That’s why MOSFETs that feature elevated SOA are critical in today’s hot swap applications where designers must specify the most robust and reliable components to meet server demands. We designed the AONS30300 with high SOA capabilities and low on-resistance to help our customers meet these challenging application requirements and uptime goals,” said Peter H. Wilson, Sr. Director of MOSFET product line at AOS.
