Features

Description

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.
