SCRs - Modules Procurement Notes

Verify the specific suffix HPSA1 against official Infineon documentation to confirm exact manufacturing lot attributes and compliance status. Ensure that the ordering code matches the required electrical parameters and package variant before procurement. Cross-reference the datasheet version to validate all technical specifications are current.

SCRs - Modules Selection Notes

Select this component for applications requiring 2600 V blocking capability and phase control functionality. Evaluate the thermal management system to maintain junction temperature within the 125 °C limit given the 0.17 K/W thermal resistance. Confirm that the gate trigger requirements align with the driving circuit design for reliable turn-on under varying load conditions.

SCRs - Modules Part Context

This part belongs to the Infineon Power Block family of 50 mm press-pack thyristors. It shares the physical form factor and mounting interface with other modules in the series, such as the TZ400N26KOF and TT285N16KOF, facilitating standardized mechanical design across different voltage and current ratings within the same product line.

SCRs - Modules Replacement Considerations

Direct replacements must match the 50 mm press-pack footprint and 2600 V rating. Consider variants like TT150N26KOF if the HPSA1 suffix denotes specific packaging or testing variations not critical to the application. Verify thermal resistance and surge current ratings when substituting with similar models.
