600 V Second-Generation Super-Junction MOSFETKN Series:Faster Switching Enabled, While Maintaining Low Noise Performance
2017.12.21
Super-junction MOSFETs are MOSFETs with dramatically lower ON-resistance and gate charge (Qg) compared with planar MOSFETs. ROHM’s series of 600 V super-junction MOSFETs boast such characteristics as fast operation, low noise, and high efficiency, and are currently advancing toward a second generation.
They are contributing to improved efficiency in a variety of power conversion circuits, from power supplies to PFCs and the like.
Fast, Low-noise KN Series
The KN series maintains the low-noise performance of the EN series, while further improving high-speed performance. Of course, the ON-resistance remains low. To improve the switching speed, Rg and Qgd were reduced. Consequently switching losses were cut, and efficiency improved. In comparisons of inverter circuit applications,
switching losses were reduced by 40% over those of the EN series.
The product lineup of the KN series is shown below. As with the EN series, multiple packages are available for each model.
