recovery power diodes in four basic configurations. The
semiconductors are electrically isolated from the metal base,
allowing common heatsinks and compact assemblies to be
built. Application includes power supplies, battery chargers,
welders, motor controls and general industrial current
rectification. These modules are intended for those
applications where fast recovery characteristics are required.
