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.
