π-MOS IX Planar Power MOSFETs Toshiba π-MOS IX Planar Power MOSFETs offer high-efficiency and low noise in a compact TO-220SIS package. π-MOS IX MOSFETs provide optimal performance due to the double-diffused process design adjustment. With an optimized chip design, the π-MOS IX components provide 5dB lower peak EMI noise than the previous π-MOS VII series, while maintaining the same efficiency level. These N-channel power MOSFETs offer high design flexibility, reducing workloads. In addition, the π-MOS IX series provides the same rated avalanche current and rated drain current (DC), making it simple to replace existing MOSFETs.
