MG12400D-BN2MM

Overview

The MG12400D-BN2MM is a 1200V IGBT module manufactured by Littelfuse. It features an IGBT3 chip utilizing Trench+Field Stop technology, designed for low saturation voltage and positive temperature coefficient characteristics. The module supports fast switching with short tail current. Official documentation identifies it as a 1200V 400A IGBT module, while some distributor listings cite 580A ratings. It is housed in a D package configuration.

Feature Summary

• Utilizes IGBT3 chip technology with Trench+Field Stop design
• Features low saturation voltage and positive temperature coefficient
• Designed for fast switching performance with short tail current

Applications

• Industrial motor drives
• Power conversion systems
• Off-highway electric vehicle power distribution

Procurement Notes

Verify the specific datasheet version before procurement, as official Littelfuse documentation lists the current rating as 400A, whereas some third-party distributors list 580A. Confirm the exact package type and pinout compatibility with your existing design. Note that this product may be listed as no longer manufactured or obsolete in certain channels. Ensure the source provides the original Littelfuse datasheet rather than generic descriptions to avoid specification discrepancies.

Selection Notes

Select this module for applications requiring high voltage isolation at 1200V and robust thermal stability due to its positive temperature coefficient. The IGBT3 technology offers improved switching efficiency compared to older generations. Consider the 400A nominal current rating from official specifications when sizing the system. Verify if the alternative 580A rating cited by some vendors applies to specific conditions or represents a different variant.

Part Context

This component belongs to the Littelfuse MG series of IGBT modules, which are engineered for high-power industrial applications. The series utilizes advanced semiconductor chips to deliver reliable performance in demanding environments. The BN2MM suffix typically denotes specific packaging and terminal configurations within the product family.

Replacement Considerations

Check for direct substitutes within the Littelfuse MG series that share the same voltage and current ratings. Verify pin-to-pin compatibility and thermal interface requirements. No specific public substitute part numbers are confirmed in the provided data.
