Procurement Notes

Verify the specific suffix designation when ordering, as it may indicate packaging variations or compliance status. Confirm RoHS compliance requirements against project specifications, noting that some variants in this series may not meet all environmental directives. Cross-reference the manufacturer part number with distributor databases to ensure availability and correct identification before finalizing procurement plans.

Selection Notes

Select this component based on the required regulated current value and maximum operating voltage. Ensure the thermal management design accommodates the 500mW power dissipation rating at the highest expected ambient temperature. Verify that the DO-7 package dimensions fit the printed circuit board layout constraints and that the lead spacing matches the target mounting holes.

Part Context

This device belongs to the 1N5283-1 through 1N5314-1 series of current regulating diodes manufactured by Microchip Technology. These components share common electrical characteristics and packaging styles, differing primarily in their specific regulated current ratings. The series provides a standardized solution for simple current control applications across various industrial and commercial electronics.

Replacement Considerations

Compatible substitutes include other 1N5314 equivalents from different manufacturers, provided they match the 5.17mA current rating, 100V breakdown voltage, and DO-7 package footprint. Verify pinout compatibility and thermal performance metrics before substitution.
