FEATURES
• Very low Qrr and t
• Lead (Pb)-free
• Designed and qualified for industrial level
BENEFITS
• Reduced RFI and EMI
• Reduced snubbing
DESCRIPTION
HEXFRED® 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 of burrs or other protrusions. Apply a thin even film or thermal grease to mounting surface.
Gradually tighten each mounting bolt in 5 to 10 lbf ⋅ in steps until desired or maximum torque limits are reached.
