Procurement Notes

Verify the specific ordering suffix and manufacturer documentation when sourcing this component. Confirm that the received part matches the 1N5295-1 designation and adheres to the specified electrical parameters. Check for any recent product change notifications regarding assembly sites or packaging updates to ensure compatibility with existing designs.

Selection Notes

Select the 1N5295-1 when a fixed current regulation around 902µA is required within a 100V limit. Ensure the circuit design accounts for the 500mW power dissipation capability and the operating temperature range. Consider the DO-7 through-hole package for board layout constraints. Verify that the load conditions do not exceed the maximum limiting voltage of 1.25V under all operating scenarios.

Part Context

This component belongs to the 1N52xx series of current regulator diodes produced by Microchip Technology. These devices are silicon-based junction diodes designed specifically for maintaining a constant current flow regardless of voltage variations across the device, provided the voltage remains within the specified limits. They serve as simple, cost-effective alternatives to active current sources in many analog applications.

Replacement Considerations

Consult the official Microchip datasheet for the 1N5283-1N5314 series to identify compatible substitutes. Verify that any alternative part number offers matching current regulation (approx. 902µA), voltage ratings (100V), and package type (DO-7). Cross-reference specifications to ensure thermal and electrical performance aligns with the original design requirements.
