PD - 94169A HFB20HJ20C TM HEXFRED Ultrafast, Soft Recovery Diode Features V = 200V R Reduced RFI and EMI Reduced Snubbing I = 20A F(AV) Extensive Characterization of Recovery Parameters Hermetic t = 20ns Surface Mount rr Description TM 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. Absolute Maximum Ratings Parameter Max.
