ROHM Semiconductor 80V Automotive MOSFETs for 48V Systems
ROHM Semiconductor 80V Automotive MOSFETs for 48V Systems provide 48V vehicle subsystems that need a practical balance of compact size, current capability, and mounting reliability. This series meets the rising power demands of modern automotive electrical architectures. To improve power delivery efficiency in high-load applications, designers are replacing conventional 12V rails with 48V systems. This option makes the lineup a strong fit for designs such as main inverter control circuits, electric motors, and electric water pumps, where board space, thermal performance, and long-term reliability all matter.
The package strategy is a major differentiator. ROHM offers the series in HPLF5060 and DFN3333 formats, giving designers two ways to reduce board area while maintaining automotive-grade robustness. The HPLF5060 package measures 4.9mm x 6.0mm and offers a smaller footprint than widely used TO-252-class packages, while gull-wing leads help improve solder joint formation and PCB mounting reliability. The DFN3333 package, at 3.3mm x 3.3mm, supports even higher-density layouts and uses wettable flank technology to improve post-solder inspection visibility and board-mount confidence in compact assemblies.
ROHM also adopts copper clip bonding to improve heat dissipation and support high-current operation, helping the AG16xFNxx series address electrically demanding 48V power paths in automotive systems. Both currently announced devices are AEC-Q101 qualified, reinforcing suitability for harsh vehicle environments. The available lineup starts with the AG160FNS4FRA in the HPLF5060 package and the AG166FNH7FRA in the DFN3333 package, covering designers who need either higher current handling or a smaller mounting footprint. As part of the EcoMOS™ silicon power MOSFET family, the series offers engineers a practical option for building smaller, more reliable 48V automotive power stages, with package choices that align with different thermal, current, and layout priorities.
