| PD-91796 PRELIMINARY HFA40HF60C Ultrafast, Soft Recovery Diode VR = 600V VF = 1.56V Qrr = 270nC HEXFRED Features TM (ISOLATED BASE) * Reduced RFI and EMI * Reduced Snubbing * Extensive Characterization of Recovery Parameters * Hermetic * Surface Mount ANODE COMMON CATHODE ANODE di(rec)M/dt = 345 A/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.
