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=123
) Repetitive peak reverse voltage is
up to 800V.
TjMax=150
Isolated Mounting Base
High reliability by unique glass passivation
Easy Assemble by the #250 terminal Tab
Applications
AC. DC Moter Drive/AVR/Switching
for three phase rectification
