Japanese electronic parts manufacturer ROHM Semiconductor has launched a new range of medium-voltage N-channel MOSFETs featuring low ON-resistance for automotive applications, including motors for doors and seat positioning, as well as LED headlights.
ROHM has been supplying low ON-resistance MOSFETs for consumer and industrial equipment and has now extended its products to meet the requirements of the automotive sector. The components can be used in motors, including doors, seat positioning and power windows, as well as LED headlights, infotainment systems and displays and advanced driver assistance systems (ADAS).
Users can select from 10 models across three package types, depending on the application. Offered in voltage ratings of 40 V, 60 V, and 100 V, the new RF9x120BKFRA, RQ3xxx0BxFRA and RD3x0xxBKHRB incorporate a split-gate structure to achieve low ON-resistance. All the models are qualified under the AEC-Q101 automotive reliability standard, which contributes to greater miniaturization and high-efficiency operation.
The company offers compact DFN2020Y7LSAA (2.0 mm × 2.0 mm) and HSMT8AG (3.3 mm × 3.3 mm) packages for space-constrained sets like ADAS. The TO-252 (DPAK) package (6.6 mm × 10.0 mm) is available for automotive power applications. ROHM has further enhanced mounting reliability by using wettable flank technology for the DFN2020Y7LSAA package and gull-wing leads for the TO-252 package.
The company plans to expand its lineup in the future. Mass production of the DFN3333 (3.3mm × 3.3mm) and HPLF5060 (5.0 mm × 6.0 mm) packages is scheduled for October 2024, followed by 80 V products in 2025. P-channel products are also scheduled for future release.
