Nexperia 40 V low RDS(on) automotive MOSFETs in a 3×3 mm footprint for demanding powertrain applications

A global leader in Discretes, Logic and MOSFET devices, Nexperia focuses on efficiency and producing consistently reliable semiconductor components, coupled with optimized high-volume production to ensure secure supply to its customers. It manufactures more than 90 billion devices per year in its own facilities. The benchmark for ultra-compact packages, Nexperia’s ability to combine power and thermal efficiency with best-in-class quality levels meets the stringent standards set by the automotive industry.

In February 2019, Nexperia introduced a portfolio of low RDS(on) 40 V AEC-Q101 MOSFETs

targeting space-constricted, increased-power modules in demanding powertrain applications. When it comes to driving more efficient solutions, these applications are a main focus point, with power density, thermal performance and space the key areas for improvement. As automotive design engineers continue to innovate – especially in applications such as water, fuel and oil pumps, and engine filters – the focus is on reducing module size but with increasing power requirements.

Nexperia’s 40 V AEC-Q101 MOSFETs are housed in the miniature LFPAK33 package which has a footprint of only 10.9 mm² and a pitch of just 0.65 mm. These devices use Nexperia’s Trench 9 technology, which results in a reduction in RDS(on) of 48% when compared to previous technology devices, covering a range of applications from 30 W up to 300 W. BUK7M3R3-40H and BUK9M3R3-40H (Standard Level and Logic Level) devices feature an RDS(on) of just 3.3 m. They are an ideal fit for a wide range of thermally-demanding systems operating in the 30 W to 300 W range, including water, oil and fuel pumps.

Improved RDS(on) and current capability allows the LFPAK33 package to replace larger power styles at a lower cost with comparable product performance, where traditionally DPAK-packaged devices which are 80% larger than LFPAK33 devices have been used. Rugged, Trench 9 Superjunction technology also delivers a higher Avalanche capability and greater Safe Operating Area (SOA) for improved performance under fault conditions.

Nexperia’s LFPAK33 40 V MOSFET family represents the industry’s largest portfolio of devices in a 3×3 mm footprint, with an additional 16 Standard Level and Logic Level devices. Devices are qualified to AEC-Q101 exceeding the requirements of this standard by more than two times.
