NTE5742

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 Absolute Maximum Ratings: Repetitive Peak Reverse Voltage, VRRM NTE5742 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800V NTE5743 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1600V Non−Repetitive Peak Reverse Voltage, VRSM NTE5742 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 880V NTE5743 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1760V Average Output Current (50/60Hz, Sinewave), ID NTE5742 (TC = +101°C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 75A NTE5743 (TC = +93°C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 75A Surge Forward Current (Rated Load Conditions), IFSM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1000A Maximum I2t for Fusing (Rated Load Conditions), I2t . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4000A2sec 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) . . . . . . . . . . . . . . . . . . . . . . 0.30°C/W Thermal Resistance (With Thermal Compound), RthCF . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.06°C/W Electrical Characteristics: Parameter Symbol Maximum Repetitive Peak Reverse Current NTE5742 IRRM NTE5743 Maximum Forward Voltage Drop NTE5742 VFM NTE5743 Test Conditions Rating Unit TJ = +150°C, VRRM = 800V 10 mA TJ = +150°C, VRRM = 1600V 8 mA TJ = +25°C, IFM = 100A 1.15 V TJ = +25°C, IFM = 75A 1.30 V Circuit Diagram AC AC AC + − AC AC AC + − 2.600 (66.0) .709 (18.0) .630 1.575 (16.0) (40.0) M4* x 10 Screw (5 Places) 1.417 (36.0) (Note 1) .905 (23.0) 1.102** (28.0) 3.150 (80.0) *NTE5743 = M5 not M4 **NTE5743 = 1.299 (33) Note 1.
