Procurement Notes
Verify the specific part number against official manufacturer documentation before procurement. Confirm that the required voltage rating and thermal performance align with your circuit design parameters. Ensure compliance with relevant environmental directives applicable to your region. Check for any updates to the datasheet regarding mechanical dimensions or electrical characteristics prior to finalizing orders.
Selection Notes
Select this component when an 800 V blocking capability is required alongside a 1 A continuous current rating. The fast recovery time makes it suitable for high-frequency switching environments where minimizing reverse recovery losses is critical. Consider the thermal resistance and operating temperature limits to ensure reliable performance under expected load conditions.
Part Context
This component belongs to the CD214A-RS1x series of fast response rectifiers from Bourns. The series offers various voltage ratings ranging from 200 V to 1000 V, all sharing the same 1 A current rating and compact SMA-compatible package. This allows designers to standardize on a single footprint while adjusting voltage specifications based on application needs.
Replacement Considerations
Other parts within the CD214A-RS1x series such as RS1J (600V) or RS1M (1000V) may be considered if voltage requirements differ. Cross-referencing with other manufacturers' SMA packages requires verification of forward voltage, reverse recovery time, and thermal characteristics to ensure functional equivalence.
