Automotive ASFETs for Repetitive Avalanche

Guaranteed repetitive avalanche performance, automotive qualified

When using MOSFETs to power inductive loads such as driving solenoids, most circuit designs include additional components to protect the MOSFET when the load current continues to flow during switch off. This can range from highly efficient but expensive boost topologies that reuse the energy, to the less efficient but more cost-effective approach of using a freewheeling diode. The simple alternative option of a repetitive avalanche set-up has historically only been possible using planar technology. By optimizing MOSFETs to comfortably handle repetitive avalanche currents while maintaining a junction temperature below 175 °C, Nexperia offers a truly rugged device that delivers numerous system level savings.

ASFETs for Repetitive Avalanche

ASFETs for Repetitive Avalanche are designed to meet the needs of a range of automotive and inductive loads:

  • Qualified to AEC-Q101
  • Guaranteed repetitive avalanche performance, tested up to 1 billion cycles
  • Rugged silicon technology combined with thermal performance of LFPAK, ensures die temperature stays below 175 °C
  • Simplicity of using a single MOSFET reduces BOM and circuit complexity, delivering system cost and space savings
  • Modern trench alternative to older planar technologies 
  • Offers increased efficiency and faster switching in comparison to freewheeling diode approach

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.
