• Optimized for use in Welding and Switch-Mode Power Supply applications
• Industry benchmark switching losses improve efficiency of all power supply topologies
• 50% reduction of Eoff parameter
• Low IGBT conduction losses
• Latest technology IGBT design offers tighter parameter distribution coupled with exceptional reliability
• IGBT co-packaged with HEXFREDTM ultrafast, ultra-soft-recovery anti-parallel diodes for use in bridge configurations
• Lower switching losses allow more cost-effective operation and hence efficient replacement of larger-die MOSFETs up to 100kHz
• HEXFREDTM diodes optimized for performance with IGBTs. Minimized recovery characteristics reduce noise, EMI and switching losses
