SCRs - Modules Procurement Notes

Verify the specific ordering suffix to ensure correct variant selection. Confirm that the disk button form factor matches the mechanical constraints of the target assembly. Cross-reference the manufacturer part number against official distribution channels to avoid counterfeit components. Ensure compliance with RoHS directives if required by the end application standards.

SCRs - Modules Selection Notes

Select this component when an 1800 V blocking voltage and over 2 kA RMS current are necessary. Evaluate the thermal resistance requirements against the system's cooling infrastructure. Consider the 250 mA gate trigger current for driver circuit design. Compare against alternative packages if space constraints differ from the disk button footprint.

SCRs - Modules Part Context

This part belongs to Infineon's Thyristors subcategory within the broader SCR Modules product line. It utilizes standard silicon technology for reliable operation. The T940N18TOF designation serves as an alias for this specific xpsa1 variant, indicating consistent core electrical characteristics across naming conventions used in technical documentation.

SCRs - Modules Replacement Considerations

The T940N18TOF is listed as a direct alias for this component. Verify pinout and mounting hole dimensions before substituting with other 1800 V disk thyristors. Ensure equivalent RMS current ratings to maintain system safety margins.
