Automotive power MOSFETs in 5x6mm dual-side cooling package

Automotive power MOSFETs in 5x6mm dual-side cooling package

The MOSFETs are being used by Denso, a leading supplier of advanced automotive technology to all major car makers and are the first in a series of new devices.

The STLD200N4F6AG and STLD125N4F6AG are 40V devices for automotive motor-control applications, reverse-battery protection, and high-performance power switching. The 0.8mm-high PowerFLAT 5×6 DSC retains the footprint and thermally efficient bottom-side design of the standard package, while it exposes the top-side source electrode to further enhance heat dissipation. This allows a higher current rating that increases power density, enabling designers to build smaller ECUs without trading off functionality, performance, or reliability.

The STLD200N4F6AG and STLD125N4F6AG have a maximum drain current of 120A and maximum on-resistance of 1.5 mΩ and 3.0 mΩ, respectively. In addition, total gate charges of 172nC and 91nC, with low device capacitances, permit efficient switching at high operating frequencies.

These two 40V MOSFETs are the first devices in a new family using ST’s STripFET F6 series with trench-gate structure, which will offer a wide range of current and voltage ratings for automotive applications. They are specified for operation in extremely harsh conditions including under-the-hood temperatures up to 175°C and are 100% avalanche-rated and offered in a package with wettable flank leads for optimum soldering and 100% Automatic Optical Inspection. The family will be extended with STripFET F7 devices later this year.

The STLD200N4F6AG and STLD125N4F6AG have been AEC-Q101 qualified and are available now with prices starting from $1.15 for orders of 1000 pieces.
