PD -2.470A HFA80NK40C HEXFRED Ultrafast, Soft Recovery Diode TM BASE COMMON CATHODE Features Reduced RFI and EMI Reduced Snubbing Extensive Characterization of Recovery Parameters 1 ANODE 1 2 COMMON CATHODE 3 ANODE 2 VR = 400V VF(typ.) = 1V IF(AV) = 80A Qrr (typ.) = 200nC IRRM(typ.) = 6A trr(typ.) = 30ns di(rec)M/dt (typ.) = 190A/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.
