Scrs Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official datasheet to confirm compliance with RoHS3 standards and lead-free requirements. Ensure that the ordering information matches the exact pinout and thermal characteristics defined in the component documentation. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Scrs Selection Notes

Select this component when high voltage isolation and significant current carrying capacity are required in a ruggedized form factor. The TO-209AC package facilitates efficient heat dissipation through direct chassis mounting. Consider the standard recovery speed for applications where fast switching is not critical. Evaluate the gate trigger requirements to ensure compatibility with the driving circuitry capabilities.

Scrs Part Context

This SCR belongs to the 110RKI series, which is characterized by robust construction for industrial environments. The series offers various voltage and current ratings within the same package family, allowing for design flexibility. The TO-209AC format is a legacy but reliable standard for high-power discrete thyristors, ensuring compatibility with existing mounting hardware and thermal management solutions.

Scrs Replacement Considerations

The VS-110RKI120MPBF is listed as a parameter-equivalent substitute. Verify that the replacement maintains identical electrical ratings and mechanical dimensions. Confirm that any suffix changes do not alter the functional specifications or environmental compliance status.
