MUBW50-12E8

Overview

The IXYS MUBW50-12E8 is a Converter-Brake-Inverter (CBI3) module integrating a three-phase rectifier, inverter, and brake chopper. It utilizes IGBT technology with low saturation voltage and Hiperfast soft-recovery free-wheeling diodes. The input rectifier bridge supports a repetitive peak reverse voltage of 1600 V and an average forward current of 50 A at 80°C case temperature. The output inverter features IGBTs with a collector-emitter breakdown voltage of 1200 V, a continuous collector current of 90 A at 25°C, and a saturation voltage of 1.9 V to 2.4 V. The integrated brake chopper provides a 1200 V rating with a 52 A continuous current at 25°C. The module includes an NTC temperature sensor and operates within a junction temperature range of -40°C to +125°C.

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches project requirements. Review the datasheet for phase-out status and lead time constraints before finalizing procurement plans. Ensure compliance with RoHS directives and verify thermal interface material specifications for optimal heat dissipation performance.

Selection Notes

Select this module for applications requiring combined rectification, inversion, and dynamic braking capabilities. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance values. Ensure gate drive circuits accommodate the recommended ±15 V operating voltage and appropriate gate resistor values for desired switching speeds. Verify that the system's DC bus voltage remains within the 1200 V and 1600 V ratings for the respective components.
