Overview
The Infineon T690N04TOFXPSA1 is a single-chip Silicon Controlled Rectifier (SCR) module designed for high-power industrial applications. It features a nominal off-state voltage of 600 V and supports a maximum average on-state current of 900 A. The device utilizes a TO-200AA (DO-200AA) chassis mount package, facilitating robust thermal management and mechanical stability in heavy-duty environments. Key electrical characteristics include a holding current of 150 mA and an operating junction temperature range from -40°C to 125°C. This component is engineered for reliable performance in demanding power conversion systems requiring high current handling capabilities.
Feature Summary
- Single SCR structure integrated into a compact module format
- Chassis mount design optimized for efficient heat dissipation
- High current carrying capacity suitable for industrial power electronics
Applications
- Industrial motor drives and variable frequency drives
- DC power supply and rectification circuits
- Welding equipment power stages
Procurement Notes
Verify the specific suffix and marking code against the manufacturer's latest datasheet to ensure compatibility with your system requirements. Confirm that the TO-200AA package dimensions match your thermal interface and mounting hardware specifications. Check for any regional compliance certifications required for your target market before finalizing the order.
Selection Notes
Select this component when a single high-current SCR is needed in a standardized chassis mount package. Ensure the system's cooling solution can handle the thermal dissipation associated with 900 A operation. Verify that the 600 V blocking voltage aligns with the peak reverse voltages present in the circuit topology.
Part Context
This part belongs to Infineon's discrete thyristor and SCR module portfolio, targeting medium-voltage, high-current applications. The TO-200AA package is a standard form factor widely used in industrial power modules, allowing for direct replacement or integration into existing chassis-based designs without significant mechanical redesign.
Replacement Considerations
Consult official Infineon substitution guides for compatible alternatives. Ensure any substitute matches the 600 V rating, 900 A current capacity, and TO-200AA package outline to maintain mechanical and electrical integrity.
