Supporting Information
Overview
This product is an 80V power MOSFET designed for 48V power supply systems, which are becoming increasingly common in automotive applications. By adopting the DFN3333 (3.3 × 3.3mm) package, downsizing is expected compared to standard automotive MOSFET packages such as the TO-252 (6.6 × 10.0mm). The DFN3333 also features Wettable Flank Formation Technology, contributing to improved reliability on PCBs (Printed Circuit Boards). Furthermore, by adopting Copper Clip Junction Technology to enhance heat dissipation, this product is capable of handling high currents. It complies with the automotive reliability standard AEC-Q101, ensuring high reliability.
Development Background
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. To meet these needs, ROHM developed this 80V power MOSFET. This product combines compact size with high mounting reliability, meeting the diverse requirements of the evolving automotive market.
Application Examples
Automotive 48V systems: Main inverter control circuits, electric motors, electric water pumps, etc
