The MOSFETs designed for automotive use offer low resistance and high reliability in applications from LED lighting to advanced driving systems.
ROHM has introduced a new range of N-channel MOSFETs—RF9x120BKFRA, RQ3xxx0BxFRA, RD3x0xxBKHRB—that boast low ON-resistance, making them ideally suited for various automotive uses such as door and seat positioning motors and LED headlights. The company has launched sales with 10 models in three different package types and plans to expand the selection further in the future.
These MOSFETs have applications across various automotive systems, including vehicle motors used for doors, seat positioning, power windows, and LED headlights. They are also utilized in-car infotainment and display systems and play a crucial role in Advanced Driver Assistance Systems (ADAS), enhancing both functionality and safety in modern vehicles.
The automotive industry is experiencing increased electronic component use, fueled by the demand for better safety and convenience features. Additionally, there is an urgent need for enhanced power efficiency to improve fuel and electricity usage. MOSFETs, crucial for switching applications in automotive systems, are particularly in demand for their ability to reduce power loss and heat generation through lower ON resistance.
Previously known for supplying low ON-resistance MOSFETs for consumer and industrial equipment, the company claims to have adapted its advanced medium voltage processes to meet the strict reliability demands of automotive products, developing these 10 new N-channel MOSFET models. These devices, available in 40V, 60V, and 100V voltage ratings, feature a split-gate structure to ensure low ON resistance and more efficient operation in automotive settings. All models meet the AEC-Q101 automotive reliability standard, ensuring high reliability.
Users can choose from three different package sizes based on their needs. The small DFN2020Y7LSAA and HSMT8AG packages work best for small spaces like ADAS. The larger TO-252 package is for bigger automotive power needs.
