SERIES E4, E7, E8

Silicon Power Rectifiers

Edal Series E power rectifiers are stud mounted DO-4 packages. The silicon junction is carefully fitted within a glass-to-metal

hermetically sealed case, reliable operation is assured, even with extreme humidity and under other severe environmental

conditions. The series E power rectifiers are completely corrosion resistant. A double diffused, passivated junction technique is

utilized to provide stable uniform electrical characteristics. Inherent in their design is very low leakage currents and excellent surge

handling capability. Standard, bulk avalanche and fast recovery types in voltage ratings from 50 to 1500 volts PIV are available.

Series E power rectifiers are also available in reverse polarity offering extended application parameters. Edal Series E power

rectifiers are ideal for use in applications where economy, power capability and reliability are demanding considerations.
