Half-bridge LFPAK56D MOSFETs Offer 60% Lower Parasitic Inductance and Improved Thermal Performance for Space-Constrained Automotive Applications
Nexperia has announced the release of a series of half-bridge automotive MOSFETs (BUK7V4R2-40H and BUK9V13-40H) that offer 60 % lower parasitic inductance and improved thermal performance for power train, motor control, and DC/DC application. The AEC-Q101-qualified half-bridge (high side and low side) package of these devices is suitable for 3-phase automotive powertrain applications like fuel and water pumps, motor control, and DC/DC power conversion.
The LFPAK56D half-bridge makes use of the existing high volume LFPAK56D assembly processes, with proven automotive reliability. Flexible leads used by the package format helps in improving overall reliability, and an internal copper clip connection between the MOSFETs simplifies PCB designs and brings a plug-and-play style solution with exceptional current handling capability. Compared to existing dual MOSFETs for 3-phase motor control topologies, these new LFPAK56D MOSFETs occupy 30% lower PCB area and 60% lower parasitic inductance for high-performance switching applications.
Both the devices are rated at 40 V and are verified at twice the automotive AEC-Q101 specification in key tests and use highly robust Trench 9 automotive silicon process technology. The RDS(on) of the devices measures 4.2 mOhm (BUK7V4R2) and 13 mOhm (BUK9V13). The package format uses flexible leads to improve overall reliability, and an internal copper clip connection between the MOSFETs simplifies PCB designs and brings a plug-and-play style solution with exceptional current handling capability of 98 A.
