B 02/99 HFA90NH40R HEXFRED Features • Reduced RFI and EMI • Reduced Snubbing • Extensive Characterization of Recovery Parameters TM Ultrafast, Soft Recovery Diode LUG TERMINAL CATHODE a d BASE ANODE VR = 400V V F(typ.)ƒ = 1V IF(AV) = 90A Qrr (typ.) = 420nC IRRM(typ.) = 9.3A trr(typ.) = 36ns di(rec)M/dt (typ.)ƒ = 260A/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.
