Confirm the exact package type and electrical ratings against the official datasheet provided by the supplier. Ensure the component meets all required environmental and compliance standards for your specific design implementation before finalizing procurement.

Single Diodes Selection Notes

Select this component when a surface mount small signal diode is required for low-current applications. The 150 mA forward current and 200 V reverse voltage ratings define its operational limits. Consider the Round-End package compatibility with your PCB footprint and assembly equipment. Compare specifications with similar devices if higher current capacity or different packaging is needed.

Single Diodes Part Context

This component belongs to the family of small signal switching diodes used in various electronic assemblies. It is distinct from through-hole variants like the 1N459, which share similar electrical characteristics but differ in physical mounting style. The 1N459AUR variant is specifically optimized for surface mount technology, providing a compact solution for modern printed circuit board designs requiring efficient space utilization.

Single Diodes Replacement Considerations

Direct substitutes may include other surface mount small signal diodes with matching 200 V reverse voltage and 150 mA forward current ratings. Verify pinout compatibility and package dimensions, such as DO-213AA, to ensure mechanical fit. Electrical parameters must be equivalent to maintain circuit performance without modification.
