PD -2.447 rev. B 03/99 HFA140NH60 HEXFRED Ultrafast, Soft Recovery Diode TM LUG TERMINAL ANODE Features Reduced RFI and EMI Reduced Snubbing Extensive Characterization of Recovery Parameters a d BASE CATHODE V R = 600V V F(typ.) = 1.3V IF(AV) = 140A Qrr (typ.) = 490nC IRRM(typ.) = 9.3A trr(typ.) = 39ns di(rec)M/dt (typ.) = 200A/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.
