Procurement Notes

Verify the specific voltage rating suffix against the datasheet to ensure compatibility with system requirements. Confirm that the screw mount installation style matches the mechanical design. Check for any obsolescence notices or discontinuation notifications prior to finalizing procurement plans.

Selection Notes

Select this component when a 1200 V blocking capability is required alongside 300 A continuous current handling. Ensure the cooling solution can manage the 0.28 °C/W thermal resistance at the specified operating temperature range. Verify that the application does not require ESD sensitivity protections as the device is not ESD sensitive.

Part Context

This module belongs to the MSRTA series, which includes variants ranging from 1200 V to 1600 V. The 'AD' suffix denotes specific terminal configurations and packaging details within the Three Tower Iso family. It serves as a robust discrete solution for high-power industrial environments.

Replacement Considerations

Direct substitutes include other modules in the MSRTA300XXXD series with matching voltage ratings. Verify pinout compatibility before replacing existing designs.
