An extensive Baseplate Common Anode characterization of the recovery behavior for different values of current. temperature and dl/dt simplifies the calculations With Suffix " A " for common Anodes to baseplate of losses in the operating conditions. The softness of the recovery eliminates the need for a snubber in most PRODUCT SUMMARY applications. These devices are ideally suited for power IF(AV) 300A converters, motors drives and other applications where switching losses are significant portion of the total losses.
