Description
THIS IS INSULATED GATE BIPOLAR TRANSISTOR WITH ULTRAFAST SOFT RECOVERY DIODE.
Features
• UltraFast: Optimized for high operating frequencies up to 40 kHz in hard switching, >200 kHz in resonant mode
• New IGBT design provides tighter parameter distribution and higher efficiency than previous generations
• IGBT co-packaged with HEXFREDTM ultrafast, ultra-soft-recovery anti-parallel diodes for use in bridge configurations
• Industry standard
Benefits
• Higher switching frequency capability than competitive IGBTs
• Highest efficiency available
• HEXFRED diodes optimized for performance with IGBT’s . Minimized recovery characteristics require
less/no snubbing
