| PD-20376 HFA40HF120 HEXFRED Features * Reduced RFI and EMI * Reduced Snubbing * Extensive Characterization of Recovery Parameters * Hermetic * Surface Mount CATHODE ANODE TM Ultrafast, Soft Recovery Diode (ISOLATED BASE) VR = 1200V VF = 3.1V Qrr = 510 nC di(rec)M/dt = 350A/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.
