ROHM expands compact 40V/60V MOSFET lineup for automotive applications
ROHM has expanded its lineup of low-voltage (40V/60V) MOSFETs for automotive applications – such as main inverter control circuits, electric pumps, and LED headlights – by introducing latest products adopting the new HPLF5060 package (4.9mm × 6.0mm).
In recent years, automotive low-voltage MOSFETs have been trending toward smaller packages, such as the 5060-size and even more compact options. However, this miniaturisation introduces significant challenges for achieving reliable mounting, primarily due to narrow terminal spacing and leadless designs.
To address these issues, the new HPLF5060 package offers a smaller footprint compared to the widely used TO-252 package (6.6mm × 10.0mm) while enhancing board-mount reliability through the adoption of gull-wing leads. Additionally, the use of copper clip junction technology enables high-current operation, making the HPLF5060 an ideal solution for demanding automotive environments.
In addition to expanding the lineup of products using this package, mass production of the smaller DFN3333 (3.3mm × 3.3mm) package, which employs wettable flank technology, is scheduled to begin around February 2026. Furthermore, development has commenced on a TOLG (TO-Leaded with Gull-wing) package (9.9mm × 11.7mm) to further expand the lineup of high-power, high-reliability packages.
EcoMOS is ROHM’s brand of silicon power MOSFETs designed for energy-efficient applications in the power device sector. Widely utilised in applications such as home appliances, industrial equipment, and automotive systems, EcoMOS provides a diverse lineup that enables product selection based on key parameters such as noise performance and switching characteristics to meet specific requirements.
