SCRs - Modules Procurement Notes

Verify the specific suffix HPSA1 against official Infineon documentation to confirm RoHS compliance status and exact manufacturing origin. Confirm availability through authorized distributors as supply levels fluctuate. Ensure the ordering part number matches the required voltage and current ratings precisely before procurement.

SCRs - Modules Selection Notes

Select this component for applications requiring a single-phase thyristor with 1400 V blocking capability and 500 A continuous current handling. Verify that the system's thermal design can maintain the junction temperature below 125 °C under maximum load conditions. Ensure the gate drive circuit provides sufficient current exceeding 250 mA for reliable triggering.

SCRs - Modules Part Context

This module belongs to the TZ500N series of high-power thyristors from Infineon. It shares the standard 50 mm Power Block form factor with other variants in the lineup, such as the TZ500N16KOF. The series is engineered for heavy-duty industrial power conversion where reliability and high current density are critical requirements.

SCRs - Modules Replacement Considerations

Direct replacements include the TZ500N16KOF (1600V variant) if higher voltage margin is acceptable. Cross-reference with TT500N14KOFXPSA1 only if the DK module configuration is compatible with the existing mechanical assembly.
