NTE5744 & NTE5745 Powerblock Modules 3 Phase Bride Modules Description: The NTE5744 and NTE5745 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 Absolute Maximum Ratings: Repetitive Peak Reverse Voltage, VRRM NTE5744 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800V NTE5745 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1600V Non–Repetitive Peak Reverse Voltage, VRSM NTE5744 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 880V NTE5745 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1760V Average Output Current (50/60Hz, Sinewave), ID NTE5744 (TC = +103°C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100A NTE5745 (TC = +97°C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100A Surge Forward Current (Rated Load Conditions), IFSM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1200A Maximum I2t for Fusing (Rated Load Conditions), I2t . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6000A2sec Operating Junction Temperature Range, TJ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –40° to +150°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –40° to +125°C Isolation Breakdown Voltage (RMS, Main Terminal to Case, 1sec), VISO . . . . . . . . . . . . . . . . . 2500V Thermal Resistance, Junction–to–Case, RthJC (50/60Hz Sinewave, Thermal Resistance for Total Loss) . . . . . . . . . . . . . . . . . . . . . . 0.22°C/W Thermal Resistance (With Thermal Compound), RthCF . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.06°C/W Electrical Characteristics: Parameter Symbol Maximum Repetitive Peak Reverse Current NTE5744 IRRM NTE5745 Maximum Forward Voltage Drop NTE5744 VFM Test Conditions Rating Unit TJ = +150°C, VRRM = 800V 10 mA TJ = +150°C, VRRM = 1600V 20 mA 1.15 V 1.25 V TJ = +25°C, IFM = 100A NTE5745 Circuit Diagram AC AC AC + – AC AC AC + – 2.600 (66.0) .709 (18.0) .630 1.575 (16.0) (40.0) 1.417 (36.0) (Note 1) M4 x 10 Screw (5 Places) 1.102 .905 (28.0) (23.0) 3.150 (80.0) Note 1.
