Powerex General Purpose Rectifier Diodes are
designed with high locking voltage capability and
low forward voltage drop to minimize conduction
losses. These are packaged in hermetic,
ceramic Pow-R-Disc packages which can be
mounted using commercially available clamps
and heatsinks or fully assembled to a variety of
air or water cooled heat exchangers.
