Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix -1 indicates MIL-PRF-19500/463 qualification when sourcing. Confirm package type is DO-7 axial leaded. Check RoHS status as military parts may have different compliance markings. Ensure supplier provides traceability documentation for defense contracts.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed low-current source is needed without active feedback loops. Compare 1.43mA output against other variants like JAN1N5303-1 (1.76mA) if higher current is required. Ensure the 100V breakdown voltage meets circuit requirements. Verify thermal management capabilities for 475mW dissipation in enclosed environments.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN series of current regulator diodes from Microchip, formerly Microsemi. It is qualified under MIL-PRF-19500/463 standards. The base model 1N5302 exists in commercial versions, but the JAN prefix denotes military-grade screening and reliability testing for harsh environments.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JAN1N5303-1 for slightly higher current (1.76mA). Commercial equivalents like 1N5302 lack military qualification. Ensure any replacement matches the 1.43mA nominal current and DO-7 package footprint.
