• Reduced RFI and EMI

• Reduced Snubbing

• Extensive Characterization of Recovery Parameters

• Hermetic

Features

Description

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.
