FRED Pt®,
Ultrafast Soft Recovery Diode Module, 400 A
FEATURES
• Ultrafast recovery
• UL approved file E222165
• Designed for industrial level
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
BENEFITS
• Reduced RFI and EMI
• Higher frequency operation
• Reduced snubbing
• Reduced parts count
DESCRIPTION / APPLICATIONS
FRED Pt® 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 significant portion of the total losses.
