Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and delivery mode. Confirm RoHS compliance status and material categorization requirements prior to procurement. Ensure the component meets the required moisture sensitivity level and solderability standards for the intended assembly process.

Selection Notes

Select this component for applications requiring a standard recovery rectifier with a 50 V reverse voltage rating and 1.0 A continuous current capacity. Consider the DO-213AB package for automated placement compatibility. Evaluate thermal resistance values relative to the expected ambient temperature and load conditions to ensure safe operation within the specified junction temperature limits.

Part Context

This part belongs to the Vishay 1N6478 through 1N6484 series of surface-mount glass passivated junction rectifiers. The series shares common mechanical and electrical characteristics, differentiated primarily by their maximum repetitive peak reverse voltage ratings. The 1N6478 variant specifically provides a 50 V blocking capability.

Replacement Considerations

Direct substitutes within the same Vishay series include parts with identical current ratings but different voltage capabilities, such as 1N6479 or 1N6480. Verify that any replacement maintains the required reverse voltage margin and forward current capacity for the specific circuit application.
