Procurement Notes

Verify component status as this part is listed as obsolete by multiple distributors. Confirm availability through authorized channels or approved substitute part numbers before finalizing design specifications. Ensure all technical parameters match the original requirements to maintain system reliability.

Selection Notes

Select this component for applications requiring high voltage isolation and moderate current handling. Consider the TO-220AB package size for thermal management needs. Evaluate alternative parts if production volume requires currently manufactured equivalents due to the obsolete status of this specific model.

Part Context

This SCR belongs to the Crydom thyristor family, known for reliability in power electronics. The CYNB series typically offers standardized electrical characteristics for general-purpose AC control. The TO-220AB package provides a balance between power dissipation and board space efficiency.

Replacement Considerations

Check for direct substitutes with identical voltage and current ratings. Verify pin compatibility and thermal resistance values when selecting alternatives. Ensure the replacement maintains the same gate trigger characteristics for proper circuit operation.
