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 a significant portion of the total
losses.
