ROHM Unveils New 600V Super Junction MOSFETs

ROHM expanded its existing PrestoMOSTM lineup with new devices that contribute to even lower application power consumption by offering lower ON resistance than standard products.

ROHM has launched R60xxVNx series, expanding its PrestoMOSTM line-up of 600V Super Junction MOSFETs which stand out for their class-leading low ON resistance and the industry’s fastest reverse recovery time (trr).

ROHM Super Junction MOSFETsThe R60xxVNx series is optimized for power circuits in industrial equipment requiring high power, such as servers, EV charging, and base stations, as well as motor drives in white goods that are increasingly using inverters to meet the trend towards greater energy savings.

ROHM expanded its existing PrestoMOSTM lineup with new devices that contribute to even lower application power consumption by offering lower ON resistance than standard products.

The new R60xxVNx series adopts the latest proprietary processes to achieve the industry’s fastest reverse recovery time while reducing ON resistance (which is in a trade-off relationship) by up to 20% compared to equivalent products.

In terms of reverse recovery time, the new Super Junction MOSFETs inherit the breakthrough 105ns already provided by existing ROHM PrestoMOSTM products, making it possible to reduce switching loss by approximately 17% compared to other solutions. With these two features, the new devices improve efficiency in various applications.

At the same time, two even lower ON resistance models have been added to the R60xxYNx series of standard low ON resistance 600V Super Junction MOSFETs. This enables users to select the ideal product based on application requirements.

ComparisonGoing forward, ROHM will continue to expand its lineup to include new Super Junction MOSFETs featuring even lower noise performance that contributes to solving social issues (i.e., preserving the environment) by reducing power consumption in a wider range of applications.

Key FeaturesSwitching Loss

  1. Achieves class-leading low ON resistance and the industry’s fastest reverse recovery time

ROHM’s R60xxVNx series of PrestoMOSTM 600V Super Junction MOSFETs utilizes the latest processes to reduce ON resistance per unit area. Despite the difficulty in reducing ON resistance given the trade-off relationship with reverse recovery time, up to 20% lower ON resistance has been achieved compared to equivalent standard products (TO-220FM package), contributing to even lower power consumption in various applications.

  1. The industry’s fastest reverse recovery time (trr) minimizes switching loss

EfficiencyGenerally, when miniaturizing processes, basic performance such as ON resistance is improved while reverse recovery time deteriorates. In contrast, ROHM’s R60xxVNx series utilizes a proprietary high-speed technology to achieve the industry’s fastest recovery time of 105ns while maintaining lower ON resistance compared to equivalent TO-220FM package products. Eliminating wasted current reduces power loss during switching by approximately 17% over standard products.

Reverse RecoveryFurthermore, standard types such as the R60xxYNx series are offered that feature trr in the 300 to 400ns range at the same ON resistance.

Application Examples

  • EV charging stations, servers, base stations, solar power inverters (power conditioners), uninterruptible power supplies (UPS), Switched-Mode Power Supply (SMPS) and more
  • White goods such as air conditioners
  • Motor drives, power supply circuits, and the like
