ASFETs for Hotswap and Soft Start

Reliable linear mode, enhanced SOA and low RDS(on)

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 RDS(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. 

ASFETs for Hotswap and Soft Start are designed specifically to support always-on applications and equipment:

  • 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
