Power Diode Module DF75LA/LB 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=101℃) Repetitive peak
reverse voltage is up to 1600V.
