DESCRIPTION / APPLICATIONS
Modules - diode, FRED
FRED Pt® diodes are optimized to reduce losses and
EMI/RFI in high frequency power conditioning systems. The
softness of the recovery eliminates the need for a snubber in
most applications. These devices are ideally suited for HF
welding, power converters and other applications where
switching losses are significant portion of the total losses.
