Automotive MOSFETs for body control, infotainment and lighting applications

Nexperia has introduced its first portfolio of 40-100V automotive MOSFETs in industry-standard micro-lead packages designed for usage in body control, infotainment, reverse battery protection and LED lighting applications. This launch initially features 19 devices in MLPAK33-WF as well as the company's first 40V device in MLPAK56-WF, both including wettable flanks (-WF) to allow reliable solder joint inspect and AOI, thereby supplying designers with a range of MOSFETs that combine flexibility of choice, a smart cost-performance balance and the capacity to quickly ramp up high-yield production, without compromising on safety.

Vehicle architectures are evolving from ECU-based control, where each function has its own unit, to domain control, and now towards zonal architectures that consolidate applications under zonal control units. At the same time, the rise of electronics-rich vehicles and the growing incorporation of infotainment and smart features are prompting OEMs to rethink conventional automotive design requirements to support advanced, consumer-style applications within vehicles. This shift is driving increased demand for MOSFETs in DC-DC converters, inverters, and battery management systems. Operating at lower temperatures, these systems can leverage cost-effective micro-leaded devices such as the company's new MLPAK33-WF and MLPAK56-WF. Alongside their cost-performance balance, these new components fulfil the conventional needs of automotive designs: AEC-Q101 qualified, robust performance, excellent board-level reliability, and side-wettable flanks supporting AOI, making them suited to the evolving automotive landscape.

This new portfolio enables designers to select from a wide selection of micro-lead MOSFETs with various RDS(on) values, offered in standardised footprints that simplify design-in and allow engineers to seamlessly migrate between MOSFET packaging, making it simple to adopt the company's MLPAK devices. Additionally, they deliver rugged performance, excellent switching capability (with low spiking and ringing), and high power density. The high avalanche rating of these MOSFETs decreases the need to use free-wheeling diodes or bulky snubbers in switching circuits. This reduces the component count and board area, thereby helping to lower the overall system cost.

This launch marks the first of many MLPAK releases from the company, reinforcing our commitment to scalable, high-performance MOSFET solutions. Uniting proven quality and reliability with supply chain strength allows design engineers to deliver efficient systems with confidence.
