| PD - 20378B HFA35HB60C FRED Features * * * * * * Reduced RFI and EMI Reduced Snubbing Extensive Characterization of Recovery Parameters Hermetic Electrically Isolated Ceramic Eyelets Ultrafast, Soft Recovery Diode VR = 600V VF = 1.9V Qrr = 270nC di(rec)M /dt = 345A/s Description These Ultrafast, soft recovery diodes are optimized to reduce losses and EMI/RFI in high frequency power conditioning systems. An extensive characterization of the recovery behavior for different values of current, temperature and di/dt simplifies the calculations of losses in the operating conditions. The softness of the recovery eliminates the need for a snubber in most applications. These devices are ideally suited for power converters, motors drives and other applications where switching losses are significant portion of the total losses.
