SCRs - Modules Procurement Notes

Verify the exact ordering suffix against the manufacturer's official naming convention to ensure correct pinout and thermal interface specifications. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

SCRs - Modules Selection Notes

Select this component when a combined SCR and diode solution is required for phase control applications. Ensure the system design accommodates the 125 °C maximum junction temperature limit. Verify that the cooling infrastructure can maintain the case temperature within limits to support the 140 A continuous current rating effectively.

SCRs - Modules Part Context

This module is part of Infineon's Power Block family, specifically designed for high-power density applications. It shares the 34 mm form factor with other modules like TD140N22KOF but integrates both thyristor and diode functionalities. This integration simplifies circuit design by reducing component count and board space requirements compared to discrete solutions.

SCRs - Modules Replacement Considerations

Direct replacements within the same 34 mm press-fit family include models with identical or higher current ratings and matching voltage classes. Verify compatibility with existing cooling plates due to potential variations in thermal interface dimensions between different sub-series.
