Power Diode Module DF40BA 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 40Amp (Tc=119
) Repetitive peak reverse voltage is
up to 800V.
TjMax=150
Isolated Mounting Base
High reliability by unique glass passivation
Applications
AC. DC Motor Drive/AVR/Switching
for three phase rectification
