Power Diode Module DD55F series are designed for various rectifier circuits. DD55F
has two diode chips connected in series in 25mm (1inch) width package and the mounting
base is elctrically isolated from elements for simple heatsink construction. Wide voltage
rating up to, 1,600V is avaiable for various input voltage.
Isolated mounting base
Two elements in a package for simple (single and three phase) bridge
connections
Highly reliable glass passivated chips
High surge current capability
Applications
Various rectifiers, Battery chargers, DC motor drives
