Ultrafast Soft Recovery Diode
150EBU02
Features
• Ultrafast Recovery
• 175°C Operating Junction Temperature
Benefits
• Reduced RFI and EMI
• Higher Frequency Operation
• Reduced Snubbing
• Reduced Parts Count
trr = 45ns
IF(AV) = 150Amp
VR = 200V
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.
