SCRs - Modules Procurement Notes

Verify the specific voltage code suffix matches the required blocking voltage rating before ordering. Confirm that the common cathode circuit configuration aligns with the intended bridge or midpoint connection topology. Ensure heatsink mounting surfaces meet the specified flatness requirements to maintain the recommended thermal resistance values during assembly.

SCRs - Modules Selection Notes

Select this component when a dual SCR module with common cathode configuration is required for high voltage industrial environments. The TO-240AA package facilitates easy mounting on standard heatsinks while providing robust mechanical stability. Evaluate the thermal management system based on the junction-to-case thermal resistance to ensure operation within the specified temperature range.
