NTE5742 & NTE5743 3 Phase Bridge Rectifier Modules Description: The NTE5742 and NTE5743 powerblock modules are designed for threephase 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: Inverters for AC Motors Power Supply Units for DC Motors DC Power Supply Units for Battery Chargers General Purpose DC Power Supply Units Absolute Maximum Ratings: Repetitive Peak Reverse Voltage, V RRM NTE5742 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800V NTE5743 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1600V Non Repetitive Peak Reverse Voltage, V RSM NTE5742 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 880V NTE5743 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1760V Average Output Current (50/60Hz, Sinewave), I D NTE5742 (T = +101C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 75A C NTE5743 (T = +93C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 75A C Surge Forward Current (Rated Load Conditions), I . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1000A FSM 2 2 2 Maximum I t for Fusing (Rated Load Conditions), I t . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4000A sec Operating Junction Temperature Range, T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40 to +150C J Storage Temperature Range, T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40 to +125C stg Isolation Breakdown Voltage (RMS, Main Terminal to Case, 1sec), V . . . . . . . . . . . . . . . . . 2500V ISO Thermal Resistance, Junction toCase, R thJC (50/60Hz Sinewave, Thermal Resistance for Total Loss) . . . . . . . . . . . . . . . . . . . . . . 0.30 C/W Thermal Resistance (With Thermal Compound), R . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.06 C/W thCFElectrical Characteristics: Parameter Symbol Test Conditions Rating Unit Maximum Repetitive Peak Reverse Current NTE5742 I T = +150C, V = 800V 10 mA RRM J RRM NTE5743 T = +150C, V = 1600V 8 mA J RRM Maximum Forward Voltage Drop NTE5742 V T = +25C, I = 100A 1.15 V FM J FM NTE5743 T = +25C, I = 75A 1.30 V J FM 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.
