Procurement Notes

Verify the complete eight-digit part number against official documentation before procurement. Confirm that the specific voltage rating suffix matches the required application voltage. Ensure mounting hardware complies with specified torque limits for M6 and M8 screws to maintain isolation integrity and thermal performance.

Selection Notes

Select this module for applications requiring rectification with isolated packaging. Consider the 260A average forward current and 2400V blocking voltage ratings. Evaluate thermal management requirements based on the junction-to-case thermal resistance values provided in the datasheet for the specific conduction angles expected.

Part Context

This component belongs to the ND41__26 series of Dual Diode Isolated Modules from Powerex. The series offers current ratings of 260 Amperes with various voltage options ranging from 600 to 2400 Volts. These modules are designed for easy mounting on common heatsinks without additional insulation components.

Replacement Considerations

Substitute only with other ND41__26 series variants if voltage or current ratings differ. Verify dimensional compatibility and terminal configurations match the existing assembly constraints before replacing.
