Procurement Notes

Verify the specific ordering suffix (B1 FK) against the latest manufacturer documentation to ensure correct packaging and marking. Confirm that the component meets all applicable regulatory standards required for your target market before finalizing procurement orders.

Selection Notes

Select this component when high voltage blocking capability is required in a minimal PCB footprint. The 800 V rating distinguishes it from lower voltage variants within the same series. Ensure thermal management aligns with the specified derating curves for high ambient temperature environments.

Part Context

This part belongs to the CD1408-F1 series of surface mount rectifiers designed for portable communications and computing equipment. The series offers various voltage ratings from 200 V to 1000 V while maintaining a consistent 1 A current capacity and compact physical dimensions.

Replacement Considerations

Compatible substitutes include other 800 V, 1 A fast recovery diodes in SOD-87 or SOD-123 packages. Verify electrical parameters such as reverse recovery time and forward voltage drop to ensure circuit compatibility.
