These IRK series of NEW ADD-A-paks use power
diodes and thyristors in a variety of circuit configura-
tions. The semiconductor chips are electrically iso-
lated from the base plate, allowing common heatsinks
and compact assemblies to be built. They can be
interconnected to form single phase or three phase
bridges or AC controllers. These modules are intended
for general purpose high voltage applications such as
high voltage regulated power supplies, lighting
circuits, and temperature and motor speed control
circuits.
