PD-94150C HFB25HJ20 FRED Ultrafast, Soft Recovery Diode V = 200V R Reduced RFI and EMI Reduced Snubbing I = 25A F(AV) Extensive Characterization of Recovery Parameters Hermetic t = 35ns Surface Mount rr ESD Rating: Class NS per MIL-STD-750, Method 1020 These Ultrafast, soft recovery 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. Parameter Max.
