NTE NTE5745, NTE5744 Datasheet
NTE5744 & NTE5745
Powerblock Modules
3 Phase Bride Modules
Description:
The NTE5744 and NTE5745 powerblock m odules a re d esigned 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
