Procurement Notes
Verify the specific suffix (e.g., TR for tape and reel or bulk packaging) when ordering to ensure compatibility with assembly equipment. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Cross-reference datasheets from authorized distributors to validate electrical characteristics against original specifications before finalizing procurement decisions.
Selection Notes
Select this component for low-current DC rectification where axial leads are required. Ensure the circuit operating voltage remains below the 125 V reverse voltage limit. Consider thermal management requirements based on the expected forward current load. Verify that the package style matches the PCB footprint design constraints.
Part Context
This part belongs to onsemi's discrete diode portfolio, specifically categorized under general-purpose rectifiers. It serves as a fundamental passive component for converting AC to DC or protecting circuits from reverse voltage. The product line emphasizes reliability and consistent performance across various consumer and industrial electronics applications.
Replacement Considerations
Equivalent parts include other 125V 200mA axial diodes such as the 1N4937 or 1N4001 series, provided they meet the same voltage and current ratings. Verify pinout compatibility and physical dimensions before substitution.
