Current Regulation - Diodes, Transistors Procurement Notes

Verify the JAN or JANS qualification status against MIL-PRF-19500/463 requirements. Confirm the specific suffix matches the required radiation hardness level. Ensure the DO-7-2 package type aligns with the target PCB layout. Check for RoHS compliance if applicable, noting that military grades may have different environmental declarations.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 3.63 mA current source is required in harsh environments. Compare the 100 V peak voltage limit against circuit demands. Consider the -65°C to +175°C temperature range for extreme condition suitability. Evaluate the 500 mW power dissipation capability relative to thermal management constraints.

Current Regulation - Diodes, Transistors Part Context

This part is part of the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. The series offers currents from 0.22 mA to 4.7 mA. Microsemi (now Microchip) produces these devices for commercial and qualified military/space markets. The JANS suffix indicates a specific level of radiation hardness and quality control.

Current Regulation - Diodes, Transistors Replacement Considerations
