Ultrafast Soft Recovery Diode, 80 A FRED Pt®
FEATURES
• Ultrafast recovery time
• 175 °C max. operating junction temperature
• Screw mounting only
• Designed and qualified according to
JEDEC-JESD47
• Compliant to RoHS Directive 2002/95/EC
• PowerTab® package
BENEFITS
• Reduced RFI and EMI
• Higher frequency operation
• Reduced snubbing
• Reduced parts count
DESCRIPTION/APPLICATIONS
These diodes are optimized to reduce losses and EMI/RFI in
high frequency power conditioning systems.
The softness of the recovery eliminates the need for a
snubber in most applications. These devices are ideally
suited for HF welding, power converters and other
applications where switching losses are not significant
portion of the total losses.
