ROHMís Latest Generation of Dual MOSFETs:  Delivering Class-Leading Low ON Resistance
Willich-Münchheide, Germany, October 13, 2021 Ė ROHM developed dual-MOSFET products (Nch+Pch) featuring ±40V/±60V withstand voltages, QH8Mx5/SH8Mx5 series. The devices are ideal for driving motors in base stations (cooling fans) and industrial applications such as factory automation equipment requiring 24V input.

In recent years, MOSFETs are increasingly required to ensure sufficient margin against voltage fluctuations by providing 40V and 60V withstand voltages to support 24V input required for motors used in industrial equipment and base stations. Furthermore, MOSFETs are expected to deliver higher speed switching together with lower ON resistance to further improve the efficiency and miniaturization of motors.

In response, ROHM developed its 6th generation 40V/60V MOSFETs utilizing the latest precision processes for the Nch MOSFETs, following the release of the latest generation Pch MOSFETs announced at the end of last year. This combination allows ROHM to provide class-leading dual Nch+Pch MOSFETs that deliver the ±40V/±60V withstand voltage required for 24V input. Moreover, the company developed also the +40V/+60V QH8Kxx/SH8Kxx (Nch+Nch) series to support a wider range of needs. (12 models in total of Nch+Pch and Nch+Nch)

The QH8Mx5/SH8Mx5 series utilizes original latest processes to achieve class-leading lower ON resistance, 61% lower than the Pch MOSFETs in dual MOSFETs products in the ±40V class. This contributes to significantly lower power consumption in a variety of applications. Furthermore, integrating 2 devices into a single package contributes to miniaturize applications by reducing mounting area and decrease the workload required for component selection (combining Nch and Pch).

Next, ROHM will continue to expand the lineup to include 100V and 150V products for industrial equipment that demands higher voltages, contributing to the market requirements for lower power consumption and size reduction of a wide variety of applications.
