Description

HEXFREDTM 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.
