T2851N48TOHXPSA1

Overview

The T2851N48TOHXPSA1 is a high-power Silicon SCR module manufactured by Infineon Technologies, designed for demanding phase control applications. It features a rated repetitive off-state voltage (VDRM) of 4.8 kV and supports a non-repetitive peak surge current (IFSM) of 70 kA. The device utilizes a press-fit installation method within the T-15035K package, ensuring robust mechanical connection. Key electrical parameters include a maximum holding current of 350 mA and a gate trigger current of 350 mA at a voltage of 2.5 V. It operates reliably within a junction temperature range of -40°C to +125°C.

Feature Summary

• Engineered for high-voltage phase control circuits with robust surge current handling capabilities.
• Utilizes press-fit mounting technology for secure assembly without traditional screw connections.
• Constructed using silicon technology optimized for high thermal stability in industrial environments.

Applications

• High-power industrial rectifier systems
• HVDC transmission converter valves
• Large motor drive applications

Procurement Notes

Verify the specific suffix XPSA1 against official Infineon documentation to confirm RoHS compliance and material content declarations. Ensure that the ordering code matches the exact voltage and current ratings required for the target circuit design. Cross-reference the datasheet revision date to guarantee access to the most recent technical specifications and handling instructions before finalizing procurement orders.

Selection Notes

Select this component when system requirements demand a 4.8 kV blocking voltage combined with significant surge tolerance. Evaluate the thermal management strategy to ensure the junction temperature remains within the specified operational limits during continuous conduction. Confirm that the PCB or busbar design accommodates the specific dimensions and force requirements associated with the T-15035K press-fit package interface.

Part Context

This part belongs to Infineon's high-power thyristor module portfolio, specifically tailored for heavy-duty power electronics. It shares architectural similarities with other T-series modules but is distinguished by its specific 4.8 kV rating and 70 kA surge capacity. The module integrates advanced silicon planar technology to enhance reliability and switching performance in critical infrastructure applications.

Replacement Considerations

Direct substitutes may include the T2851N52TOH for higher voltage margins or the T2351N52TOH for different current ratings. Verify pin compatibility and thermal resistance characteristics before swapping components to maintain system integrity and safety standards.
