Procurement Notes

Verify the specific manufacturer designation, as the model number appears in records associated with both Mitsubishi Electric Semiconductor and Powerex Inc. Confirm that the DMA25 package and 25-pin configuration match the target PCB footprint. Ensure the component meets required lead-free and RoHS compliance standards before integration into final assemblies.

Selection Notes

Select this component when designing three-phase inverter bridges requiring 600V blocking capability and approximately 30A continuous current handling. The DMA25 package offers a suitable solution for space-constrained motor control designs. Verify thermal management requirements align with the module's dissipation characteristics for the intended operating environment.

Part Context

This component belongs to the PS21964 series of intelligent power modules. Variants such as PS21964-A and PS21964-T share similar functional descriptions regarding third-phase DC-to-AC conversion. The series utilizes fifth-generation IGBTs to achieve low-loss performance in industrial power electronics applications.

Replacement Considerations

Compatible substitutes include PS21964-A, PS21964-S, and PS21964-ST. These variants maintain the same 600V/15A or 30A specifications and fifth-generation IGBT architecture. Verify pinout compatibility and package dimensions (DMA25) before substitution.
