| Bulletin PD-20017 02/01 S1242 HEXFRED TM Features * Reduced RFI and EMI * Reduced Snubbing * Extensive Characterization of Recovery Parameters Ultrafast, Soft Recovery Diode LUG TERMINAL ANODE 1 LUG TERMINAL ANODE 2 VR = 400V VF(typ.)! = 1V IF(AV) = 320A Qrr (typ.) = 420nC IRRM(typ.) = 8.7A trr(typ.) = 45ns BASE COMMON CATHODE di(rec)M/dt (typ.)! = 280A/s Description/ Applications 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.
