Nexperia packs automotive MOSFET into space saving LFPAK56D package

To save space in automotive designs, Nexperia has introduced a series of half bridge, high side and low side automotive MOSFETs in the LFPA56D package.

The package is a space saving alternative to the conventional half bridge configuration of two MOSFETS in a standard building block which is used in motor drives, DC/DC converters and other automotive applications.

The BUK7V4R2-40H and the BUK9V13-40H half bridge MOSFETs are both supplied in an FPA56D package. There are no PCB tracks, enabling the MOSFETs to occupy 30 per cent less PCB area compared to dual MOSFETs for three-phase motor control topologies. The package also allows simple automated optical inspection (AOI) during production. The LFPAK56D half bridge uses existing high volume LFPAK56D assembly processes with proven automotive reliability, adds Nexperia.

The package format uses flexible leads to improve overall reliability, and an internal copper clip connection between the MOSFETs to simplify PCB designs. The half bridge MOSFET has a current handling capability of 98A.

The LFPAK56D half bridge offers 60 per cent lower parasitic inductance by virtue of its internal clip connection. The package also offers improved thermal performance for power train, motor control and DC/DC applications, says the company.

Both the BUK7V4R2-40H and the BUK9V13-40H use the robust Trench 9 automotive silicon process technology and are rated at 40V. They are verified at twice the automotive AEC-Q101 specification in key tests. RDS(on) for the BUK7V4R2 is 4.2mOhm and 13mOhm for the BUK9V13.

The AEC-Q101-qualified Nexperia LFPAK56D half bridge package is suitable for a range of three-phase automotive powertrain applications such as fuel and water pumps, motor control and DC/DC power conversion.   

Nexperia produces essential semiconductors, with a portfolio that includes diodes, bipolar transistors, ESD protection devices, MOSFETs, GaN FETs and analogue and logic ICs. The company is headquartered in Nijmegen, the Netherlands, and ships more than 90 billion products annually. In addition to meeting the stringent standards set by the automotive industry, the products are recognised as benchmarks in efficiency – in process, size, power and performance — with industry-leading small packages that save valuable energy and space.

Nexperia has over 12,000 employees across Asia, Europe and the US. The company is a subsidiary of Wingtech Technology and has an extensive IP portfolio and is certified to IATF 16949, ISO 9001, ISO 14001 and OHSAS 18001.
