• Qualified to MIL-PRF-19500/463 JANS reliability standards

Current Regulation - Diodes, Transistors Applications

• Spacecraft electronic systems requiring radiation tolerance
• Military avionics and defense equipment
• High-reliability industrial circuits needing stable current sources

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific JANS qualification status and radiation hardness data sheets directly from Microchip before procurement. Confirm that the DO-7-2 package dimensions match the target PCB layout requirements. Ensure compliance with all relevant export control regulations associated with space-grade semiconductor components.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required in high-radiation environments. Compare the 748 µA regulation point against circuit load requirements. Consider the 100 V breakdown voltage to ensure adequate headroom for the application's operating voltage range.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. The JANS suffix denotes a specific high-reliability, radiation-hardened variant distinct from commercial or standard military JAN versions. It serves as a current-regulation alternative to Zener diodes in similar axial packages.

Current Regulation - Diodes, Transistors Replacement Considerations

JANTXV1N5293-1 offers similar electrical characteristics but lacks the full JANS radiation hardness qualification. JAN1N5293-1 provides the base military grade without enhanced reliability screening. Verify radiation tolerance requirements before substituting.
