ROHM has introduced a new line of N-channel MOSFETs designed specifically for automotive applications, focusing on high efficiency and mounting reliability. These MOSFETs, which include models such as RF9x120BKFRA, RQ3xxx0BxFRA, and RD3x0xxBKHRB, boast low ON-resistance, making them well-suited for use in automotive motors for doors and seat positioning, as well as in LED headlights. The company has initially launched 10 models across three different package types, with plans for expansion. In response to the rising demand for electronic components in the automotive industry and the need for power efficiency to optimize fuel consumption, ROHM has extended its existing expertise in low ON-resistance MOSFETs from consumer and industrial applications to the automotive sector. The company has integrated advanced medium voltage processes and a split-gate structure to achieve enhanced performance in automotive systems.
These MOSFETs are available in 40V, 60V, and 100V voltage ratings, all meeting the AEC-Q101 automotive reliability standard. ROHM offers the components in three package types to cater to varying space and power requirements: the DFN2020Y7LSAA and HSMT8AG for compact systems like ADAS, and the TO-252 package for power-heavy applications. To further improve reliability, the DFN2020Y7LSAA incorporates wettable flank technology, while the TO-252 uses gull-wing leads. Looking ahead, ROHM plans to expand its product line, including the launch of additional packages and higher voltage MOSFETs, with P-channel variants expected in the future. These developments will help drive further miniaturization and efficiency in automotive electronics.
