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 = 600V VF(typ.)! = 1.2V IF(AV) = 140A Qrr (typ.) = 340nC IRRM(typ.) = 8.5A trr(typ.) = 33ns
BASE COMMON CATHODE
di(rec)M/dt (typ.)! = 220A/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.
