IRUD200CH20PbF
Bulletin PD-21143 05/06
Features
FRED
• Very Low Qrr and trr
• Lead-Free
Ultrafast, Soft Recovery Diode
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 significant
portion of the total losses.
Benefits
• Reduced RFI and EMI
• Higher Frequency Operation
• Reduced Snubbing
