DIODE(THREE PHASES BRIDGE TYPE)
DF75BA40/80
UL;E76102 M）
（
Power Diode Module DF75BA 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 75Amp （Tc＝107℃） Repetitive peak reverse
voltage is up to 800V.
