.. PD -2.468 rev. B 02/99 HEXFRED Features • Reduced RFI and EMI • Reduced Snubbing • Extensive Characterization of Recovery Parameters Ultrafast, Soft Recovery Diode LUG TERMINAL ANODE a d BASE CATHODE VR = 400V VF(typ.)- = 1V IF(AV) = 90A Qrr (typ.) = 420nC IRRM(typ.) = 9.3A trr(typ.) = 36ns di(rec)M/dt (typ.)- = 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...
