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.
