The 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.
1. Achieves class-leading low ON resistance and the industry’s fastest reverse recovery time
ROHM’s R60xxVNx series of PrestoMOS™ 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.
2. The industry’s fastest reverse recovery time (trr) minimizes switching loss
Generally, 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.
Thanks to these two features, the R60xxVNx series offers a higher efficiency than standard products, even when compared to evaluation boards using synchronous rectified boost circuits that pursue high efficiency (60mΩ class ON resistance products), contributing to significantly lower power consumption in applications such as solar power inverters and uninterruptible power supplies (UPS).
