DIODE^(THREE PHASES BRIDGE TYPE)
DF20BA40/80
Power Diode Module DF20BA 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 20Amp (Tc=123ˆ) Repetitive peak reverse voltage is
up to 800V.
˔ _{TjMax=150ˆ}
˔ _{Isolated Mounting Base}
˔ _{High reliability by unique glass passivation}
˔ _{Easy Assemble by the #250 terminal Tab}
