PD-40010 01/99 HFA140MD60D HEXFRED Ultrafast, Soft Recovery Diode TM Features Reduced RFI and EMI Reduced Snubbing Extensive Characterization of Recovery Parameters Anode 1 AC Cathode 2 Isolated Base VR = 600V VF(typ.) = 1.2V IF(AV) = 140A Qrr(typ.) = 360nC IRRM(typ.) = 8.0A trr(typ.) = 35ns di(rec)M/dt (typ.) = 230A/µs 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.
