Description
HFA35HB60 is part of the International Rectifier HiRel family of products. These 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 soft-
ness 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.
