TZ500N16KOFHPSA1

SCRs - Modules Overview

The TZ500N16KOFHPSA1 is a single phase control thyristor module from Infineon Technologies, part of the Power Block series. It utilizes pressure contact technology within a 50 mm package. Key electrical parameters include a repetitive peak reverse voltage (VRRM) and direct current blocking voltage (VDRM) of 1600 V. The average forward on-state current (ITAVM/TC) is rated at 500 A at 85 °C case temperature. The maximum junction temperature (Tvj) is 125 °C. On-state voltage drop (VT0) is 0.9 V at maximum junction temperature. The critical rate of rise of on-state current ((diT/dt)cr) is 200 A/µs. The surge current rating (ITSM) for 10 ms is 14,500 A.

SCRs - Modules Feature Summary

• Single SCR topology designed for phase control applications
• Pressure contact construction for robust mechanical connection
• Integrated thermal interface material (TIM) for optimized heat transfer

SCRs - Modules Applications

• Industrial motor drives
• HVDC transmission systems
• High-power rectifier bridges

SCRs - Modules Procurement Notes

Verify the specific suffix HPSA1 against official datasheets to confirm component specifications. Check manufacturer lifecycle status as some variants may be marked as not recommended for new designs. Ensure compatibility with existing cooling systems due to the 125 °C junction temperature limit. Confirm screw mounting requirements match the TZ50 package dimensions.

SCRs - Modules Selection Notes

Select this module when high current capacity and 1600 V blocking capability are required in a compact 50 mm form factor. Compare ITAV ratings against thermal management capabilities to ensure operation within the 85 °C case temperature limit. Evaluate diT/dt performance against circuit inductance to prevent device failure during turn-on. Verify that the single SCR configuration meets the system topology requirements.

SCRs - Modules Part Context

This component belongs to Infineon's Power Block family of high-power thyristor modules. These modules are engineered for demanding industrial environments requiring high reliability. The TZ500N series specifically targets applications needing substantial current handling in a standardized package size. The HPSA1 suffix indicates specific manufacturing or testing variations within the standard TZ500N16KOF product line.

SCRs - Modules Replacement Considerations

Direct replacements include the base model TZ500N16KOF if the TIM application method is compatible. Verify pinout and mechanical dimensions against alternative 50 mm single SCR modules from other manufacturers. Ensure equivalent ITAV and VRRM ratings are met by any substitute part.
