TZ400N24KOFHPSA1

SCRs - Modules Overview

The TZ400N24KOFHPSA1 is a high-power thyristor module manufactured by Infineon Technologies, designed for phase control applications. It features a single SCR configuration within the Power Block series and utilizes a 50 mm press-fit package topology. The device is constructed using silicon technology and supports a repetitive peak reverse voltage of 2400 V. Key electrical parameters include a maximum on-state voltage drop (VT0) of 1.35 V at maximum junction temperature, a gate trigger current (Igt) of 150 mA, and a holding current (Ih) maximum of 200 mA. The module is rated for a forward average current (ITAVM/TC) of 400 A at an ambient temperature of 85 °C with a 180° electrical conduction angle. It withstands a surge current (IFSM/ITSM) of 11,000 A for 10 ms at maximum junction temperature. Thermal resistance from junction to case (RthJC) is specified at 0.065 K/W under standard conditions.

SCRs - Modules Procurement Notes

Verify the specific suffix HPSA1 against official Infineon documentation to confirm material composition and environmental compliance status. Ensure that the ordering code matches the exact voltage rating and package variant required for the target application. Cross-reference the datasheet revision date to guarantee access to the most recent technical specifications and reliability data before finalizing procurement orders.

SCRs - Modules Selection Notes

Select this component when a 2400 V blocking capability and 400 A continuous current rating are required in a compact 50 mm form factor. Confirm that the system design accommodates the 150 mA gate trigger current requirement. Evaluate the thermal management solution to ensure the junction temperature remains within the 125 °C limit under worst-case operating conditions, considering the specified RthJC value.

SCRs - Modules Part Context

This part belongs to Infineon's Power Block series of thyristor modules, which are standardized for high-power industrial applications. The TZ400N24KOFHPSA1 represents a specific voltage variant within the TZ400N family, distinguished by its 2400 V rating compared to other versions like the 2600 V or 2200 V models. It shares the same physical footprint and general electrical characteristics as siblings in the series, differing primarily in voltage stress tolerance.

SCRs - Modules Replacement Considerations

Direct replacements must match the 50 mm press-fit package and 2400 V rating. Verify compatibility with existing cooling structures. Check if alternative parts require different gate drive currents or have varying thermal resistance values that might impact the system's thermal design.
