Introduction
The new CoolMOSTM CE is the fourth technology platform of Infineon’s market leading high voltage power MOSFETs designed according to the revolutionary superjunction (SJ) principle in the 500V class. 500V CE portfolio provides all benefits of a fast switching superjunction (SJ) MOSFET while keeping ease of use and implementation. The complete CE series of MOSFETs achieve very low conduction and switching losses, and can make applications more efficient, more compact, lighter and thermally cooler.
This application note will describe the fundamental differences between a SJ MOSFET and a standard MOSFET. Additionally, all features and benefits impacting the target applications will be described. Furthermore, these features will be illustrated from both a theoretical point of view and in hardware measurements. It will also be shown that CoolMOSTM CE is a cost effective alternative compared to standard MOSFETs, which enables reaching higher efficiency levels while offering an attractive price/performance ratio.
