Description
HEXFREDTM 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.

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 lbfin steps
until desired or maximum torque limits are reached. Module
