ROHM has developed the “AG16xFNxx Series,” a lineup of 80V power MOSFETs designed for 48V power supply systems, which are becoming increasingly common in automotive applications.
In the automotive sector, power demand is increasing, particularly in high-end vehicle models. 48V power supply systems are gaining attention as a highly efficient alternative to conventional 12V power supply systems. With widespread adoption expected around 2030, there is a growing need for 80V power MOSFETs that can achieve even lower power losses than standard 100V devices.
ROHM’s new products are expected to enable downsizing compared to standard automotive MOSFET packages such as the TO-252 (6.6×10.0mm) by adopting the HPLF5060 (4.9×6.0mm) and DFN3333 (3.3×3.3mm) packages.
The HPLF5060 features Gull-Wing Leads, while the DFN3333 features Wettable Flank Technology, contributing to improved reliability on PCBs (Printed Circuit Boards). Furthermore, by adoptingCopper Clip Junction Technology to enhance heat dissipation, these devices are capable of handling high currents. All models comply with the automotive reliability standard AEC-Q101, ensuring high reliability.
Mass production ofnew products began in April 2026 for the AG160FNS4FRA (HPLF5060) and the AG166FNH7FRA (DFN3333) (sample price: $3.5/unit, excluding tax). Online sales have also started, and the products are also available for online purchase through online distributors such as DigiKey and Farnell.
The product lineup of these packages will be further expanded in the near future. In addition, development of TOLG (TO-Leaded with Gullwing, 9.9×11.7mm) packaged products has begun, with continued expansion of the lineup of high-power, high-reliability 80V MOSFETs.

Terminology
Gull-Wing Leads
A terminal structure that spreads outwards from both sides of the package. It provides higher mounting reliability. It is called “Gull-Wing” because its appearance resembles the wing of a seagull.
Wettable Flank Technology
A technology for plating the sides of the lead frame on bottom electrode packages such as QFN and DFN to improve mounting reliability.
Copper Clip Junction Technology
A technology that uses copper clips (flat metal bridges) to connect chips and lead frames directly, replacing the conventional wire bonding method.
