NTE5742 & NTE5743
3 Phase Bridge Rectifier Modules
Description:
The NTE5742 and NTE5743 powerblock modules are designed for three−phase full wave rectification
and contain six diodes connected in a three−phase bridge configuration. The mounting base of the
module is electrically isolated from the semiconductor elements for simple heatsink construction.
Applications:
D Inverters for AC Motors
D Power Supply Units for DC Motors
D DC Power Supply Units for Battery Chargers
D General Purpose DC Power Supply Units
