MIXA81H1200EH

Overview

The MIXA81H1200EH is a 1.2 kV IGBT module utilizing IXYS XPT technology, designed for high-power industrial applications. It features a 3-phase full bridge inverter configuration with four elements. The device supports a continuous collector current of 120 A and a maximum power dissipation of 390 W. Key electrical parameters include a collector-emitter breakdown voltage of 1200 V, a gate-emitter maximum voltage of 20 V, and an operating temperature range from -40°C to +150°C. It employs screw mount installation within an isolated E3 package.

Feature Summary

• Utilizes IXYS XPT (eXtended Plate Technology) silicon for optimized switching performance and low conduction losses.
• Features an isolated E3 package design suitable for direct thermal management via baseplate mounting.
• Integrates a complete three-phase inverter bridge structure within a single compact module housing.

Applications

• Industrial motor drives and variable frequency drives
• Uninterruptible power supply (UPS) systems
• High-frequency power conversion equipment

Procurement Notes

Verify the specific suffix EH against official Littelfuse/IXYS documentation to confirm pinout compatibility and thermal interface specifications. Ensure that the procurement channel provides valid traceability for this discontinued series component. Cross-reference the datasheet revision history to confirm the accuracy of the 390 W power dissipation rating under your specific cooling conditions.

Selection Notes

Select this module for applications requiring robust 1200 V blocking capability and high current handling up to 120 A. The XPT technology offers a balance between switching speed and forward voltage drop. Consider the E3 package dimensions for PCB or chassis layout constraints. Verify that the drive circuit can support the required 20 V gate voltage limits for reliable operation.

Part Context

This component belongs to the MIXA81 series of three-phase IGBT modules manufactured by IXYS, now part of Littelfuse. The series is characterized by its use of advanced trench gate and field stop technologies. These modules are engineered for demanding power electronics environments where reliability and efficiency are critical operational requirements.

Replacement Considerations

Official sources list the MIXA81H1200EH as a discontinued product. Potential substitutes must be sourced from current IXYS/Littelfuse portfolios. Any replacement must match the 1200 V rating, 120 A current capacity, and E3 package footprint. Electrical parameter verification is mandatory before integration.
