Nexperia ASFET

Whether it is in the cloud or at the edge, we truly live in a 24/7 world. So much of our daily lives depend on rack-based computers, communications and storage systems that are always-on. Ensuring these systems do not experience any power disruption and to protect the components on replacement boards when they are inserted into a live system, it is essential that in-rush current is carefully controlled. In normal MOSFETs, strong SOA and low R_DS(on) are mutually exclusive. Offering both capabilities in a single device, Nexperia’s specific MOSFETs for Hotswap and Soft Start are optimized for a non-stop world. 

Key features

• Enhanced SOA (safe operating area)
• Designed to manages in-rush current effectively and reliably
• Strong linear mode performance
• Copper clip packaging for performance and robust operation 

Additional features

• MOSFETs with a strong linear mode performance and enhanced Safe Operating Area (SOA) are required to manage in-rush current effectively and reliably when capacitive loads are introduced to the backplane
• Once a replacement board is safely powered up, the MOSFET is turned fully ON. In this mode of operation, a low RDS(on) value is of primary importance, helping to keep temperatures down and system efficiency at a maximum

Applications

• Rack based computer and storage systems
• Hotswap for communication infrastructure
• High performance rack-/blade based server
• Hotswap for blade server
