Description
The IRK.L132 series of INT-A-pak uses fast recovery
power diodes in four basic configurations. The semicon-
ductors are electrically isolated from the metal base, al-
lowing common heatsinks and compact assemblies to be
built. Application includes power supplies, battery charg-
ers, welders, motor controls and general industrial current
rectification. These modules are intended for those appli-
cations where fast recovery characteristics are required.
