ASFETs for Repetitive Avalanche

Nexperia ASFETs for Repetitive Avalanche offer a 40V_DS to 60V_DS maximum drain-source voltage, 16I_D to 40I_D drain current range, and 7.9Q_GD gate-drain charge. ASFETs are fully automotive qualified to AEC-Q101 and offer high robustness, reliability, and LFPAK copper clip package technology. Nexperia ASFETs for Repetitive Avalanche are ideal for 12V, 24V, and 48V automotive systems, repetitive avalanche topologies, and engine control applications.

Automotive ASFETs

Nexperia Automotive ASFETs are Application-Specific MOSFETs optimized for specific use cases. As designers push the boundaries of application performance, it is increasingly crucial to understand how the MOSFET will be used in the application. In the past, a standard power switch with a given Figure of Merit (R_DS(on) x Q_g) would essentially work in any application. However, to address specific application requirements or functionality, optimizing a set of MOSFET parameters is increasingly necessary to match those requirements. For example, applications may require enhanced linear mode performance or repetitive avalanche functionality. Nexperia combines proven MOSFET expertise with broad application understanding to create an expanding range of Application-Specific MOSFETs.
