ROHM develops 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 capable of delivering even lower power losses than standard 100V devices.
ROHM’s new products enable downsizing in comparison 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, which contributes to improved reliability on PCBs (Printed Circuit Boards). Furthermore, by adopting Copper 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.
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.
Application Examples
Automotive 48V systems: Main inverter control circuits, electric motors, electric water pumps, etc.
