30V MOSFET has safe operating area for 12V hot swap
The AONS32310 30V MOSFET from Alpha and Omega Semiconductor has a maximum Rds(on) of 1.05mΩ for hot swap and e-fuse designs

Alpha and Omega Semiconductor has launched a 30V MOSFET with low on-resistance and a high Safe Operating Area (SOA) for hot swap and e-fuse applications.

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 AONS32310 delivers high robustness with a 30V MOSFET in a DFN 5x6 package with a maximum Rds(on) on resistance of 1.05mΩ at an applied Gate-Source Voltage equal to 10VGS.

“High reliability is an essential metric in datacenter infrastructure. The Hot Swap MOSFET is one of the critical components that must be robust and reliable to meet server demands. AONS32310 has high SOA with low on-resistance to meet these demanding application requirements,” said Peter Wilson, director of product marketing at Alpha and Omega Semiconductor.
