Procurement Notes

Verify the manufacturer designation carefully, as this component is associated with both Powerex Inc. and Mitsubishi Electric Semiconductor due to historical corporate relationships. Confirm that the specific suffix '4S' corresponds to the required package variant and electrical specifications before procurement, ensuring alignment with the intended design parameters.

Selection Notes

Select this component when a compact solution for three-phase inverter bridges is required. The integration of fifth-generation IGBTs offers efficiency benefits over older technologies. Ensure the system voltage does not exceed the 600V rating and current demands remain within the 15A limit for reliable operation.

Part Context

This part belongs to the PS21964 series of hybrid modules. Variants such as PS21964-A, PS21964-T, and PS21964-ST share similar core functionalities but differ in packaging and terminal configurations. The PS21964-4S specifically denotes the DMA25 package style within this family of motor controllers.

Replacement Considerations

Compatible substitutes include PS21964-A, PS21964-T, and PS21964-ST. Verify pinout compatibility and thermal requirements when substituting, as package differences may affect mounting and heat dissipation strategies.
