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 dIF/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.
