STMicroelectronics STLD200N4F6AG and STLD125N4F6AG automotive power MOSFETs

Click2Contact

STMicroelectronics has introduced MOSFET devices in the PowerFLAT 5x6 dual-side cooling (DSC) package, enabling increased power density in automotive electronic control units (ECUs). The STLD200N4F6AG and STLD125N4F6AG are 40 V devices for automotive motor-control applications, reverse-battery protection and high-performance power switching.

The 0.8 mm-high PowerFLAT 5x6 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 or performance.

The STLD200N4F6AG and STLD125N4F6AG, with a maximum drain current of 120 A and maximum on-resistance of 1.5 and 3.0 mΩ, respectively, ensure high energy efficiency and help simplify system thermal management. Total gate charges of 172 and 91 nC, with low device capacitances, permit efficient switching at high operating frequencies.

The MOSFETs are specified for operation in harsh conditions, including under-the-hood temperatures up to 175°C. The devices are 100% avalanche-rated and offered in a package with wettable flank leads for optimum soldering and 100% automatic optical inspection.
