SCRs - Modules Procurement Notes

Verify the specific suffix HPSA3 against official Infineon documentation to confirm manufacturing lot details and compliance status. Ensure that the ordering information matches the exact technical specifications required for the target application, as minor variations may exist between production batches or regional releases.

SCRs - Modules Selection Notes

Select this component when a single-phase thyristor with 1800 V blocking capability and 800 A continuous current is required. Consider the 70 mm package dimensions for mechanical integration and verify that the cooling system can maintain the junction temperature within the specified 125 °C limit under maximum load conditions.

SCRs - Modules Part Context

This module belongs to the TZ800N series of high-power thyristors manufactured by Infineon Technologies. The series is engineered for demanding industrial power electronics applications requiring reliable phase control. The HPSA2/HPSA3 suffixes typically denote specific packaging or testing configurations within the broader product line.

SCRs - Modules Replacement Considerations

Direct replacements must match the 1800 V rating, 800 A current capacity, and 70 mm press-pack footprint. Verify compatibility with existing gate drive circuits regarding the 250 mA trigger current requirement.
