ROHM is launching low ON-resistance MOSFETs to improve fuel efficiency and power consumption due to the increase in electrical components in automobiles, contributing to the supply of high-efficiency automotive electrical components.

ROHM announced on the 31st that it has developed automotive Nch MOSFETs △RF9x120BKFRA △RQ3xxx0BxFRA △RD3x0xxBKHRB featuring low ON resistance.

It is ideal for various motors used in automotive door locks, seat positions, and LED headlights. Ten models are available in three packages, and the lineup is expected to expand further in the future.

The new products are available in 40V, 60V, and 100V voltage ratings, all of which utilize a split-gate structure to achieve low ON resistance, contributing to high-efficiency operation in automotive applications. All models also comply with the AEC-Q101 automotive reliability standard, ensuring high reliability.

The package is available in three types depending on the purpose. For applications with small mounting areas, such as advanced driver assistance systems (ADAS), the small packages DFN2020Y7LSAA (2.0mm×2.0mm) and HSMT8AG (3.3mm×3.3mm) are optimal.

We also have the TO-252 (DPAK) package (6.6mm x 10.0mm), which is widely used in power supplies for automotive applications.

The DFN2020Y7LSAA package terminal adopts Wettable Flank formation technology, and the TO-252 package terminal adopts a gull wing shape, improving mounting reliability.

The new product is currently in mass production with a monthly production capacity of 10 million units (a total of 10 models). Production is conducted at ROHM Co., Ltd. (Shiga Plant) for front-end processes, and ROHM Apollo Co., Ltd. (Fukuoka) and ROHM Integrated Systems (Thailand) Co., Ltd. (Thailand) for back-end processes.

Online sales have also begun, and products can be purchased from online parts distribution sites such as Chip 1 Stop™ and CoreStaff™.

Going forward, ROHM plans to expand its lineup of medium-voltage Nch MOSFETs for automotive use.

In January 2024, the company plans to sequentially mass-produce products in the DFN3333 package (3.3mm x 3.3mm) and HPLF5060 package (5.0mm x 6.0mm), and in 2025, it plans to sequentially mass-produce 80V products, and it also plans to add Pch products.

We will continue to expand our lineup to contribute to high-efficiency operation and miniaturization of automotive applications.
