ROHM has introduced a new lineup of 600V Super Junction MOSFETs, expanding its portfolio with the R60xxXNx and PrestoMOS™ R60xxWNx series. The new devices are designed to address the growing demand for higher efficiency, increased power density, and improved thermal performance in AI server power supplies, data centers, and industrial equipment.

As AI computing and industrial automation drive higher power consumption, power supply designers face increasing pressure to improve efficiency while reducing system size and heat generation. ROHM’s latest Super Junction MOSFETs target these challenges by combining low-loss performance with compact surface-mount packaging that supports automated assembly and improved thermal management.

The expanded lineup introduces two industry-standard surface-mount packages:

  • DFN8080-5L (8.0 × 8.0 × 0.85 mm)
  • TOLL (11.68 × 9.9 × 2.3 mm)

These low-profile packages offer excellent heat dissipation while enabling higher power density and more compact power supply designs.

The new MOSFET families feature:

  • 600V Super Junction technology
  • Gate threshold voltage (VGS(th)) of 3 V to 5 V for compatibility with standard gate-drive circuits
  • Improved admittance characteristics compared with previous-generation R60xxYNx and PrestoMOS™ R60xxVNx devices
  • Lower conduction and switching losses
  • Surface-mount footprints compatible with existing industry-standard designs

The standardized package footprints also simplify product replacement and support second-source procurement strategies.

ROHM offers two series optimized for different design priorities:

R60xxXNx Series

  • 21 device variants
  • High-speed switching performance
  • Designed for applications prioritizing compatibility and versatile operation

PrestoMOS™ R60xxWNx Series

  • 11 device variants
  • Class-leading high-speed reverse recovery performance
  • Optimized for designs requiring maximum efficiency and lower switching losses

The new MOSFETs are intended for a broad range of high-voltage power conversion systems, including:

  • AI server power supplies
  • Data center power infrastructure
  • Industrial power supplies
  • Industrial automation equipment
  • High-power AC-DC converters
  • Other high-density power conversion applications
