Features
Ultrafast, soft and noise-free recovery
Low forward voltage drop meaning very
small conduction losses
ECOPACK®2 compliant component for
D²PAK on demand
Description
Dual center tap fast recovery epitaxial diodes
suited for switch mode power supply and high
frequency DC to DC converters.
Packaged either in TO-220AB and D2PAK, this
device is particularly intended for secondary
rectification inside SMPS with high space and
power density.
