Automotive ASFETs for half-bridge configurations

60% lower parasitic inductance and improved thermal performance

A series of half-bridge (high side & low side) MOSFETs constructed in the space-saving LFPAK56D package format. The half-bridge configurationis a standard building block for many automotive applications including motor drives and DC/DC converters. The LFPAK56D half-bridge occupies 30% lower PCB area compared to dual MOSFETs due to the removal of PCB tracks whilst also permitting simple automated optical inspection (AOI) during production. Utilising existing high volume LFPAK56D assembly processes, with proven automotive reliability. The package format uses flexible leads to improve overall reliability, as well as an internal copper clip connection between the MOSFETs simplifying PCB design, offering a plug and play style solution with exceptional current handling capability to your application.

Features and Benefits
