Description
HEXFREDTMdiodes 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.

„ Mounting surface must be smooth, flat, free or burrs or other
protrusions. Apply a thin even film or thermal grease to mounting
surface. Gradually tighten each mounting bolt in 5-10 lbf•in steps
until desired or maximum torque limits are reached. Module
