| PD -2.464 rev. B 01/99 HFA70NC60C HEXFRED Features * Reduced RFI and EMI * Reduced Snubbing * Extensive Characterization of Recovery Parameters TM Ultrafast, Soft Recovery Diode VR = 600V VF(typ.) = 1.2V IF(AV) = 70A Qrr (typ.) = 210nC IRRM(typ.) = 6A trr(typ.) = 30ns di(rec)M/dt (typ.) = 180A/s Description HEXFRED 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.
