Edal Industries went on to develop hermetically sealed power rectifiers in packages of D04, D05, D08, D09, and T03. These units were made to the highest quality standards using exotic materials such as a molybdenum discs to support the silicon chip with the closest CTE match, thus preventing thermal fatigue. All die are gold plated to assure excellent bonding and glass passivated for protection from the environment. The unique design of the all-copper base construction assures maximum thermal and electrical conductivity and allows for high mounting torque.
