en.Wedoany.com Reported - ROHM Semiconductor has launched the AG16xFNxx series of 80V power MOSFETs, specifically optimized for automotive 48V power systems. This series is designed to meet the growing power demands of modern vehicles while improving efficiency and reducing the footprint of power conversion stages.
As the automotive industry shifts toward higher-power electrical architectures, 48V systems are increasingly becoming a viable alternative to traditional 12V networks, particularly in high-end and electrified vehicles. This transition is expected to accelerate in the coming years, driving demand for power semiconductors with lower conduction and switching losses than the commonly used 100V MOSFETs. ROHM Semiconductor developed the AG16xFNxx series to meet these requirements by offering 80V devices tailored for the 48V automotive voltage range.
The new MOSFETs are available in two compact package options: the HPLF5060 package (4.9 mm × 6.0 mm) and the DFN3333 package (3.3 mm × 3.3 mm). Compared to traditional automotive MOSFET packages such as TO-252 (6.6 mm × 10.0 mm), both options achieve a significant reduction in size. The smaller footprint allows designers to increase power density and reduce the overall dimensions of electronic control units and power modules.
ROHM Semiconductor employs packaging technologies aimed at improving reliability and thermal performance. The HPLF5060 package features Gull-Wing Leads to enhance solder joint robustness, while the DFN3333 package utilizes Wettable Flank Technology to facilitate automated optical inspection and improve PCB connection reliability. Additionally, these devices incorporate Copper Clip Junction Technology to enhance heat dissipation, enabling the MOSFETs to support high-current operation under demanding automotive conditions.
All products in the AG16xFNxx series comply with the automotive reliability standard AEC-Q101, making them suitable for vehicle applications with stringent safety and reliability requirements. Typical applications include main inverter control circuits, electric motors, electronic water pumps, and other subsystems operating on 48V vehicle architectures.
The AG160FNS4FRA in the HPLF5060 package and the AG166FNH7FRA in the DFN3333 package began mass production in April 2026. ROHM Semiconductor also plans to expand the product portfolio with additional devices, currently developing high-power models in the TOLG package format. The new products are part of the company's EcoMOS silicon power MOSFET series, which is designed to provide energy-efficient switching solutions for automotive, industrial, and consumer applications.
