NTE5742 & NTE5743
Powerblock Modules
3 Phase Bride Modules
Description:
The NTE5742 and NTE5743 powerblock modules are designed for threephase full wave rectification
and contain six diodes connected in a threephase bridge configuration. The mounting base of the
module is electrically isolated from the semiconductor elements for simple heatsink construction.
