Procurement Notes
Verify the specific suffix DN against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Cross-reference the part number with official Powerex catalogs to avoid confusion with similar T62 series variants that may have different voltage or current ratings.
Selection Notes
Select this component when a 400 V blocking voltage and approximately 400 A continuous current are required in a compact disk form factor. Consider the standard recovery speed for non-switching applications. Evaluate the thermal management requirements based on the T62 package's heat dissipation capabilities. Confirm compatibility with existing gate drive circuits regarding the 150 mA trigger current specification.
Part Context
This SCR belongs to the Powerex T62 family, known for robust performance in high-power semiconductor applications. The T62 series offers various voltage and current combinations within a standardized disk button package, facilitating easy integration into existing power module designs. This specific model targets applications needing reliable rectification at moderate voltages and high currents.
Replacement Considerations
Consult official Powerex substitution guides for direct equivalents. Verify that any alternative SCR matches the 400 V rating, ~392.5 A current capacity, and T62 package dimensions. Ensure the replacement maintains compatible gate trigger characteristics and thermal resistance values.
