Description
These series of INT-A-paks uses high voltage power
diodes in two basic configurations. The semiconductors
are electrically isolated from the metal base, allowing
common heatsinks and compact assemblies to be built.
They can be interconnected to form single phase or three
phase bridges and the single diode module can be used
in conjunction with the thyristor modules as a freewheel
diode. These modules are intended for general purpose
applications such as battery chargers, welders and plat-
ing equipment and where high voltage and high current
are required (motor drives, etc.).
