Some of the text files within the PDF file
1. Optimized for use in Welding and Switch-Mode Power Supply applications
2. Industry benchmark switching losses improve efficiency of all power supply topologies
3. 50% reduction of Eoff parameter
4. Low IGBT conduction losses
5. Latest technology IGBT design offers tighter parameter distribution coupled with exceptional reliability
1. Lower switching losses allow more cost-effective operation and hence efficient replacement of largerdie
MOSFETs up to 100kHz
2. Of particular benefit in single-ended converters and Power Supplies 150W and higher
3. Reduction in critical Eoff parameter due to minimal minority-carrier recombination coupled with low onstate losses allow maximum flexibility in device application
