Ultrafast Soft Recovery Diode 50EBU04 Features Ultrafast Recovery 75 C Operating unction Temperature Screw Mounting Only Lead-Free Plating Benefits Reduced RFI and EMI Higher Frequency Operation Reduced Snubbing Reduced Parts Count t rr = 60ns I F(AV) = 50Amp V R = 400V 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.
