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

How to use parametric search?

  • You can choose the number of results per page: 10, 25, 50, 100 or all results.
  • You can use the filters in the second row to narrow down the selection. Click on one or more values in the lists you want to select. Or use the sliders by dragging the handlers or fill in the fields.
  • The common characteristics are parameters with the same value for all type numbers.
  • You can find more information about a type number by hovering over the type number and click on one of the links in the pop-up.
  • You can compare two or more type numbers by selection the checkboxes for the type numbers and click on Compare. All other rows will be hidden.
  • To hide the row with filtering options, click on the grey bar with arrows below the options.
  • To add or remove columns with parameters click on the Add/Remove parameters button on the top right. You can check the columns you want to see.
  • You can change the order of the columns by dragging and dropping the columns to the desired position.
  • You can download the results of your (filtered) selection to Excel by clicking the Download Excel button.
