Rohm launches 600V super junction MOSFETs
Rohm has developed a new lineup of 600V super junction MOSFETs, the R60xxXNx and R60xxWNx series to meet the demands of increasing processing loads and higher efficiency within limited space.
The new products - R60xxXNx series and PrestoMOS R60xxWNx series - add surface-mount DFN8080-5L (8.0 × 8.0 × 0.85mm) and TOLL (11.68 × 9.9 × 2.3mm) packages to the existing package lineup. With compact, low-profile designs and excellent heat dissipation, these packages are suitable for applications that require space savings and higher power density, including power supplies for AI servers and industrial equipment.
In terms of characteristics, the gate threshold voltage (VGS(th)) required to turn on the MOSFET is set to a 3V to 5V range widely used in standard products, supporting a broad range of drive conditions. In addition, improved admittance characteristics deliver greater versatility and lower loss, compared with conventional R60xxYNx series and PrestoMOS R60xxVNx series.
Surface-mount packages having market common footprint ensure excellent versatility while making it easier to consider replacement in existing power supply circuits and select second sources.
The lineup consists of 21 models in the high-speed switching R60xxXNx series and 11 models in the PrestoMOS R60xxWNx series that offers class-leading* high-speed recovery characteristics. Users can select the optimal product according to their application needs, from products suited for designs prioritising compatibility to those suited for designs emphasizing lower loss.
Mass production began sequentially in June 2026. Online sales have also started with TOLL package products (Applicable Part No: R6020XNJ2, R6038XNJ2, R6049XNJ2, R6055XNJ2, R6024WNJ2, R6035WNJ2), which are available through online distributors such as DigiKey.
