DF50BA40/80

Power Diode Module DF50BA is designed for three phase full wave rectification, which

has six diodes connected in a three phase bridge configuration. The mounting base of the

module is electrically isolated from semiconductor elements for simple heatsink

construction Output DC current is 50Amp

（Tc＝114℃） Repetitive peak reverse voltage

is up to 800V.

●
