The development of an Nch MOSFET that contributes to high-efficiency operation of applications with industry-leading low ON resistance is expected to contribute to the development of power supplies for industrial equipment and various motor drive devices.

ROHM announced on the 13th that it has developed 13 products (40V/60V/80V/100V/150V) of the Nch MOSFET "RS6xxxxBx/RH6xxxxBx series" that are optimal for driving applications that operate on 24V/36V/48V power systems, such as base station/server power supplies and motors for industrial and consumer equipment.

The new product has achieved the industry's lowest ON resistance (Ron) of 2.1 mΩ, which is approximately 50% lower than existing products, by adopting the HSOP8/HSMT8 package with low resistance Cu (copper) clip connection, along with improved device performance through process miniaturization.

In addition, through improvement of the gate structure, Qgd (gate-to-drain charge), which is generally a trade-off with ON resistance, was reduced by approximately 40% compared to existing products.

Accordingly, switching loss and conduction loss can be reduced, greatly contributing to high-efficiency operation of each application.

As an example of high-efficiency operation, the new product achieved industry-leading power efficiency (approximately 95% at peak) in the output current range during normal operation when comparing power efficiency on an industrial equipment power evaluation board.

The new product will begin mass production in January 2023 at a monthly production capacity of 1 million units (sample price 500 yen/unit, excluding tax), and can be purchased from online parts distribution sites such as CoreStaff and Chip 1 Stop.
