Ultrafast Soft Recovery Diode
Features • Ultrafast Recovery • 175°C Operating Junction Temperature 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.
