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.
