TT520N22KOFHPSA2

SCRs - Modules Overview

The TT520N22KOFHPSA2 is a high-power silicon thyristor module from Infineon Technologies, belonging to the Power Block series. It utilizes 60 mm press-pack technology and is designed for phase control applications. The device features a repetitive peak reverse voltage of 2200 V and an average on-state current rating of 520 A at 180° electrical conduction. Key thermal parameters include a junction-to-case thermal resistance of 0.058 K/W and a maximum junction temperature of 125 °C. Electrical characteristics specify a critical rate of rise of on-state current of 200 A/µs and a non-repetitive surge current capability of 14500 A for 10 ms.

SCRs - Modules Procurement Notes

Verify the specific ordering suffix HPSA2 against official Infineon documentation to confirm material composition and compliance status. Confirm availability as this component may be subject to end-of-life notices or limited production runs. Ensure that the press-pack form factor matches the mechanical constraints of the intended heatsink assembly before procurement.

SCRs - Modules Selection Notes

Select this module when high voltage blocking capability and significant current handling are required in a compact footprint. The 60 mm package size dictates specific cooling interface requirements compared to smaller modules. Evaluate the thermal resistance and surge current ratings against the system's fault conditions to ensure reliable operation within the specified junction temperature limits.

SCRs - Modules Part Context

This part belongs to Infineon's Power Block family of high-power semiconductor modules. It shares the 60 mm press-pack form factor with other variants in the series, such as the TT260N22KOFHPSA1 and TT430N22KOFHPSA2, differing primarily in current and voltage ratings. The naming convention indicates a thyristor with 2200 V rating and 520 A current capacity.

SCRs - Modules Replacement Considerations

Direct replacements within the same package and electrical class include the TT520N22KOF. Other variants in the 60 mm series like the TT430N22KOFHPSA2 offer lower current ratings but may fit mechanically if derating is acceptable. Verify pinout and thermal interface compatibility before substitution.
