HEXFREDTM
PRELIMINARY
PD-20371A
HFA35HB120C
Ultrafast, Soft Recovery Diode
Features
• Reduced RFI and EMI
• Reduced Snubbing
• Extensive Characterization of Recovery Parameters
• Hermetic
• Electrically Isolated
• Ceramic Eyelets
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.
