12 low-on-resistance ROHM Nch+Pch MOSFETs
Suitable for driving motors for industrial equipment and base stations
Equipped with ±40V and ±60V voltage resistance, enabling miniaturization and quiet operation.


Recently, in response to the 24V input used in industrial equipment and base station motors, MOSFETs are required to have a voltage rating of 40 or 60V with respect to voltage fluctuation margins. In addition, to increase motor efficiency and miniaturization, expectations for low on-resistance and high-speed switching operation have increased for MOSFETs.

On the 1st, ROHM developed the 'QH8Mx5 (±40V withstand voltage) and SH8Mx5 (±60V withstand voltage)' series of Nch+Pch MOSFETs compatible with 24V input. Two devices are integrated into a single package, such as SOP8 or TSMT8, reducing mounting area. This enables device miniaturization and reduces the effort required for device selection. In particular, the QH8Mx5 series, which has a ±40V withstand voltage, has an on-resistance that is up to 61% lower in the Pch portion and up to 39% lower in the Nch portion compared to standard products.

When the new product is combined with ROHM’s ‘BD63001AMUV and BD63002AMUV’ 3-phase brushless motor pre-driver ICs or ‘BM62300MUV’ 3-Hole sensor 3-phase brushless motor pre-driver ICs, further miniaturization, lower power consumption, and quiet driving of the motor become possible.

Two series suitable for large-scale industrial and consumer FAN applications began mass production in March of this year with a production capacity of 1 million units per month. The sample price is 250 yen per unit (excluding tax), and they can be purchased from online retailers such as Chip One Stop and Core Step.
