MG1775S-BN4MM

Overview

The Littelfuse MG1775S-BN4MM is a 1700V, 75A IGBT power module utilizing IGBT3 Trench+Field Stop technology for the switch and EMCON 3 technology for the integrated free-wheeling diode. It features low turn-off losses with short tail current and a positive temperature coefficient for VCE(sat). The module supports high-frequency switching with an operating junction temperature range of -40°C to 125°C and a maximum junction temperature of 150°C. Key electrical parameters include a collector-emitter saturation voltage of 2.45V typ at 75A/25°C, gate threshold voltage of 5.8V typ, and insulation test voltage of 4000V AC. It weighs 160g and requires M6/M5 torques of 3-5 N·m and 2.5-5 N·m respectively.

Procurement Notes

Verify component authenticity by cross-referencing the part marking and lot number against official Littelfuse documentation. Confirm that the assembly site code matches authorized manufacturing locations. Ensure compliance with RoHS standards as indicated in the agency approvals section. Check for any specific handling requirements related to the bulk pack configuration and weight specifications during logistics planning.

Selection Notes

Select this module for designs requiring 1700V blocking capability and 75A continuous current at 80°C case temperature. Consider the thermal resistance values of 0.24 K/W for the IGBT and 0.45 K/W for the diode when designing heatsink solutions. Evaluate the gate charge and internal gate resistor values to optimize driver circuit design for the specified switching energies and times.

Part Context

This component belongs to the Littelfuse MG series of power modules, specifically designed for industrial and commercial power conversion applications. The 'MG' prefix denotes a general power module format, while the '17' indicates the 1700V voltage rating and '75' specifies the 75A current class. The suffix 'BN4MM' identifies the specific package type and assembly details within this product family.

Replacement Considerations

Direct replacement verification requires matching the 1700V/75A ratings, pinout configuration, and thermal interface dimensions. Compare switching energy curves and thermal impedance characteristics to ensure equivalent performance in the target application. Verify that alternative components meet the same insulation voltage and tracking index requirements.
