| PD-20371A PRELIMINARY HFA35HB120C Ultrafast, Soft Recovery Diode VR = 1200V VF = 4.46V Qrr = 370nC HEXFRED Features TM (ISOLATED BASE) * Reduced RFI and EMI * Reduced Snubbing * Extensive Characterization of Recovery Parameters * Hermetic * Electrically Isolated * Ceramic Eyelets ANODE COMMON CATHODE ANODE di(rec)M/dt = 380A/s 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.
