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.
