FRED
Ultrafast Soft Recovery Diode Module, 200 A
FEATURES
Very low Qrr and trr
Lead (Pb)-free
Designed and qualified for industrial level
Reduced RFI and EMI
Reduced snubbing
DESCRIPTION
FRED 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 dl/dt
simplifies the calculations of losses in
the operating conditions. The softness
of the recovery eliminates the need for
a snubber in most applications.
