B 02/99 HFA90NH40 HEXFRED Features • Reduced RFI and EMI • Reduced Snubbing • Extensive Characterization of Recovery Parameters TM Ultrafast, Soft Recovery Diode LUG TERMINAL ANODE a d BASE CATHODE VR = 400V VF(typ.
)ƒ= 1V IF(AV) = 90A Qrr (typ.
) = 420nC IRRM(typ.
) = 9.
3A trr(typ.
) = 36ns di(rec)M/dt (typ.
)ƒ = 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 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.
